Understanding Wavelength, Frequency, and Speed

When delving into the fascinating world of wave physics, it's crucial to grasp the fundamental relationship between a wave's wavelength, frequency, and speed. These three properties are intrinsically linked, and understanding their connection allows us to predict and analyze wave behavior across various mediums. In this article, we will explore how to calculate the wavelength of a wave given its frequency and speed, using the specific example of a wave with a frequency of 466 Hz and a speed of 343 m/s. This exploration will not only provide a practical application of the wave equation but also deepen your understanding of wave mechanics. Specifically, we'll address the question: What is the wavelength of a wave with a frequency of 466 Hz and a speed of 343 m/s? and walk you through the process of finding the correct answer.

To fully appreciate the significance of this calculation, let's first define each of these properties:

  • Wavelength (λ): This refers to the distance between two consecutive crests (or troughs) of a wave. It is typically measured in meters (m). Think of it as the physical length of one complete wave cycle.
  • Frequency (f): This represents the number of complete wave cycles that pass a given point per unit of time. It is measured in Hertz (Hz), where 1 Hz is equal to one cycle per second. Essentially, it tells you how often the wave oscillates.
  • Speed (v): This is the rate at which the wave propagates through a medium. It is measured in meters per second (m/s). The speed indicates how quickly the wave is traveling.

The relationship between these three properties is described by the fundamental wave equation:

The Wave Equation: v = fλ

The wave equation is the cornerstone of wave mechanics, providing a concise mathematical relationship between the speed (v), frequency (f), and wavelength (λ) of a wave. This equation, expressed as v = fλ, states that the speed of a wave is equal to the product of its frequency and wavelength. This relationship is not merely a formula; it encapsulates a deep connection between these fundamental wave properties. Manipulating this equation allows us to solve for any one of these variables if the other two are known. This is particularly useful in a variety of contexts, from calculating the wavelengths of radio waves to understanding the behavior of sound waves in different media. Understanding and applying the wave equation is essential for anyone studying physics, acoustics, or any field where wave phenomena are important.

To understand the equation better, let's break it down:

  • v represents the speed of the wave.
  • f represents the frequency of the wave.
  • λ represents the wavelength of the wave.

This equation is incredibly versatile and can be rearranged to solve for any of the three variables. For instance, if we want to find the wavelength (λ), we can rearrange the equation as follows:

λ = v / f

This rearranged equation tells us that the wavelength of a wave is equal to its speed divided by its frequency. This simple yet powerful relationship allows us to calculate the wavelength if we know the speed and frequency, which is precisely what we need to do in our problem.

Applying the Wave Equation to Our Problem

Now that we have a firm grasp of the wave equation and the relationship between wavelength, frequency, and speed, let's apply this knowledge to solve the specific problem at hand: determining the wavelength of a wave with a frequency of 466 Hz and a speed of 343 m/s. This is a practical application of the concepts we've discussed and will demonstrate how the wave equation can be used to solve real-world problems. By working through this example, you'll gain a deeper appreciation for the power and utility of this fundamental equation in physics.

We are given:

  • Frequency (f) = 466 Hz
  • Speed (v) = 343 m/s

We need to find the wavelength (λ). Using the rearranged wave equation:

λ = v / f

Substitute the given values:

λ = 343 m/s / 466 Hz

λ ≈ 0.736 m

Therefore, the wavelength of the wave is approximately 0.736 meters. Now, let's compare this result with the given options.

Analyzing the Answer Choices

After calculating the wavelength to be approximately 0.736 meters, the next crucial step is to compare our calculated result with the provided answer choices. This step is essential not only for identifying the correct answer but also for reinforcing our understanding of the problem-solving process. By carefully examining each option, we can verify the accuracy of our calculations and ensure that we have correctly applied the relevant concepts. This process of comparison and analysis is a vital skill in physics and other quantitative fields, as it encourages critical thinking and helps prevent errors. Furthermore, understanding why the other options are incorrect can deepen our understanding of the underlying principles and potential pitfalls in problem-solving.

The provided options are:

A. 1.35 m B. 0.74 m C. 6.25 × 10⁻⁶ m D. 1.6 × 10⁵ m

Comparing our calculated wavelength (0.736 m) with the options, we can see that option B, 0.74 m, is the closest value. This is within a reasonable margin of error, likely due to rounding during the calculation. The other options are significantly different, indicating that they are incorrect.

  • Option A (1.35 m) is almost double our calculated value, suggesting a possible error in either the application of the formula or the initial understanding of the problem.
  • Option C (6.25 × 10⁻⁶ m) is extremely small, which would correspond to a very high frequency, not matching our given frequency and speed.
  • Option D (1.6 × 10⁵ m) is an extremely large value, which is unrealistic for a wave traveling at 343 m/s with a frequency of 466 Hz.

Therefore, by comparing our calculated value with the provided options and analyzing the discrepancies, we can confidently identify the correct answer.

The Correct Answer and Its Significance

After carefully applying the wave equation and comparing our result with the provided options, we can confidently conclude that the correct answer is B. 0.74 m. This result represents the wavelength of a wave with a frequency of 466 Hz and a speed of 343 m/s. Understanding the significance of this answer involves recognizing what the wavelength physically represents and how it relates to the wave's other properties.

The wavelength of 0.74 meters tells us the distance over which the wave completes one full cycle of oscillation. In simpler terms, it's the length of one complete wave pattern as it travels through a medium. This measurement is crucial because it provides insights into how the wave interacts with its environment. For example, the wavelength of a sound wave influences the pitch we perceive, while the wavelength of light determines its color.

The fact that we were able to calculate this wavelength using the wave equation highlights the power and utility of this fundamental relationship in physics. By knowing the speed and frequency of a wave, we can precisely determine its wavelength, and vice versa. This ability is essential in numerous applications, including:

  • Acoustics: Understanding the wavelengths of sound waves is critical for designing musical instruments, concert halls, and noise-canceling technologies.
  • Optics: The wavelengths of light determine the colors we see and are fundamental to the design of lenses, telescopes, and other optical instruments.
  • Telecommunications: Radio waves, microwaves, and other electromagnetic waves used in communication systems are characterized by their wavelengths, which influence their propagation and interaction with antennas.
  • Medical Imaging: Techniques like MRI and ultrasound rely on the interaction of waves with the body, and understanding the wavelengths involved is essential for interpreting the results.

In summary, the correct answer of 0.74 m not only solves the specific problem but also underscores the broader importance of wavelength as a fundamental property of waves and its relevance in various scientific and technological applications. This underscores the significance of understanding the relationship between wavelength, frequency, and speed.
