What is the Speed of Light equation?

The Speed of Light equation describes the relationship between the speed of light, its wavelength, and its frequency. The correct equation is expressed as c = wavelength * frequency, where 'c' represents the speed of light in a vacuum, 'wavelength' denotes the distance between successive crests of a wave, and 'frequency' refers to how many wave cycles occur per unit time.

This equation is fundamental to understanding wave phenomena, including electromagnetic waves such as light. By recognizing that the speed of light is constant in a vacuum, this relationship demonstrates that as the wavelength increases, the frequency must decrease in order to maintain the equality. Conversely, if the frequency increases, the wavelength must decrease.

The other options do not correctly represent the relationship between these terms. The first option incorrectly uses addition, while the second option inverts the multiplication necessary for the relationship. The last option suggests a subtraction operation that does not apply in this context, as speed, wavelength, and frequency are multiplicative rather than additive or subtractive. Understanding this multiplication aspect is crucial for solving many physics and chemistry problems relating to wave behavior.
