Introduction

In the realm of physics, waves are a fundamental concept that govern the behavior of various phenomena, from sound and light to water and seismic waves. The study of waves involves understanding the relationships between their key properties, including wavelength, frequency, and speed. In this article, we will delve into the world of wave equations and explore which one can be rearranged to calculate the frequency of a wave.

Wave Equations: A Brief Overview

Before we dive into the specifics of each equation, let's briefly review the three fundamental wave equations:

• Wavelength: The distance between two consecutive points on a wave that are in phase with each other.
• Frequency: The number of oscillations or cycles per second, measured in Hertz (Hz).
• Speed: The rate at which a wave propagates through a medium, measured in meters per second (m/s).

The three wave equations are:

• A. $\text{wavelength} = \frac{\text{frequency}}{\text{speed}}$
• B. $\text{frequency} = \frac{\text{wavelength}}{\text{speed}}$
• C. $\text{wavelength} = \text{speed} \times \text{time}$

Rearranging the Equations

To determine which equation can be rearranged to calculate the frequency of a wave, we need to examine each equation and see if we can isolate the frequency variable.

Equation A: $\text{wavelength} = \frac{\text{frequency}}{\text{speed}}$

This equation is already in a form that allows us to solve for frequency. By multiplying both sides of the equation by speed, we can isolate the frequency variable:

$\text{wavelength} \times \text{speed} = \text{frequency}$

This equation can be rearranged to solve for frequency:

$\text{frequency} = \text{wavelength} \times \text{speed}$

Equation B: $\text{frequency} = \frac{\text{wavelength}}{\text{speed}}$

This equation is already in a form that allows us to solve for frequency. By multiplying both sides of the equation by speed, we can isolate the frequency variable:

$\text{frequency} \times \text{speed} = \text{wavelength}$

This equation can be rearranged to solve for frequency:

$\text{frequency} = \frac{\text{wavelength}}{\text{speed}}$

Equation C: $\text{wavelength} = \text{speed} \times \text{time}$

This equation is already in a form that allows us to solve for wavelength. By dividing both sides of the equation by speed, we can isolate the wavelength variable:

$\frac{\text{wavelength}}{\text{speed}} = \text{time}$

This equation cannot be rearranged to solve for frequency.

Conclusion

In conclusion, both Equation A and Equation B can be rearranged to calculate the frequency of a wave. However, Equation B is the most straightforward and intuitive form, as it directly relates frequency to wavelength and speed.
