Question

Quizplus · Accepted Answer

Refraction of light involves a change in the speed of light as it travels from one medium to another. This change in speed results in a change in the wavelength of the light, while the frequency remains the same. This can be explained by the formula c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency. If the speed of light changes, either the wavelength or the frequency must also change to keep the equation balanced. Since the speed of light is different in different media, the change in wavelength (and therefore the change in direction) occurs during refraction.
