   White light is dispersed by a glass prism into the colors of the visible spectrum. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light).

   May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

   What is the wavelength and frequency of visible light?

   • Since visible light is a form of a wave, it is defined by its characteristic wavelength and frequency. The visible light spectrum is located within a wavelength range of 380 to 740 nanometers (nm) or a frequency range of 405 to 790 terahertz (THz). Consists of seven colors – violet, indigo, blue, green, yellow, orange, and red.

   Is light a wave?

   • Most of us were taught at school that light is a wave. This is because it does things that waves do. So, for example, waves undergo interference. To understand this, imagine that you’ve just dropped two stones in a still pond. Each of those stones will create ripples, with the water creating waves that move up and down.

   Is the wavelength of a light wave inversely proportional to its frequency?

   • The wavelength of a light wave is inversely proportional to its frequency. Light is often described by it's wavelength in a vacuum. Light ranges in wavelength from 400 nm on the violet end to 700 nm on the red end of the visible spectrum. Phase differences between light waves can produce visible interference effects.

    A red waistcoat absorbs all the colours in white light, except the red, which is reflected back to the environment. So a person looking at this waistcoat will only see the colour reflected by the waistcoat, i.e. red. Black, on the other hand, indicates that our eyes do not perceive any light rays.
