What is the formula for calculating wavelength?

The formula for calculating wavelength is based on the relationship between wave speed, frequency, and wavelength. The correct choice states that the wavelength (λ) can be determined by dividing the speed of light (c) by the frequency (f). This reflects a fundamental principle of wave mechanics applicable to electromagnetic waves, including light.

In this formula, the speed of light is a constant in a vacuum, approximately 299,792,458 meters per second, and the frequency represents the number of oscillations or cycles that occur per second. By rearranging this relationship, if you know the speed of light and the frequency of the wave, you can easily compute the wavelength, which indicates the distance between successive peaks of the wave.

This understanding is crucial, especially in areas such as telecommunications, radio transmission, and optics, where knowing the wavelength aids in the design and understanding of various technologies and systems.
