It reasonable to treat light as a ray instead of a wave in everyday situations because "the wavelengths of light are so short that they wave effects are negligible".
The distance between the two crests or troughs of the light wave is known as the wavelength of light. Using the Greek letter lambda , it is identified. As a result, wavelength refers to the separation between one wave's crest or dip and the following wave.
