The phenomenon where light separates into different colors due to varying speeds of refraction, creating a rainbow-like effect.
The entire range of electromagnetic wavelengths emitted or absorbed by different objects, encompassing visible light as well as non-visible forms like infrared and ultraviolet.
Dispersion of light through water droplets refers to the phenomenon where sunlight is refracted, reflected, and internally reflected inside individual water droplets, resulting in the separation of white light into its constituent colors, forming a rainbow.
The speed of electromagnetic waves, denoted by ‘c’, is the speed at which electromagnetic radiation propagates in a vacuum, such as space. Its value is approximately 299,792,458 meters per second (m/s).
The formula for the speed of electromagnetic waves is:
c = λ x f
where,
c = speed of light in a vacuum (m/s)
λ = wavelength of the electromagnetic wave (m)
f = frequency of the electromagnetic wave (Hz)
