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".
<h3>What is wavelength of light?</h3>
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.
Some properties of wavelength of light are-
- The wavelengths and frequency of these distinct light colors vary.
- The visible spectrum's longest wavelength and lowest frequency are found in red light.
- The visible spectrum's violet color has the shortest wavelength and highest frequency.
- A small band of wavelengths, roughly 380 to 730 nm, make up visible light.
- Our eyes interpret these wavelengths as various hues.
- If only one wavelength or a small range of wavelengths are seen, they are perceived as having a specific hue.
The four properties of light waves are-
- reflection,
- refraction,
- diffraction and
- interference.
