what actually is wavelength of a light apart from definition
Answers
Wavelength of a light is the minimum size of a particle you can observe.
A particle is observed when light is reflected off it. Hence, you cannot observe any object that is smaller than the wavelength of light.
Wavelength of Light Formula:
As light has the properties of a wave and a particle, it can be expressed in two equations:
ν=λf………………..(1)
E=hf…………….(2)
Where,
ν is the velocity of the light.
λ is the wavelength of the light.
f is the frequency of the light.
E is the energy of the light wave.
h is the Planck’s Constant i.e. 6.64×10−34joule⋅second
Here, the first equation denotes to the wave nature of the light and the second equation denotes to particle nature of the light.
Wavelength of Visible Light:
Wavelength of the Visible Light ranges between 400 nm to 700 nm and here we come to know the wavelength of various colours of the visible spectrum of light.
The spectrum of visible light has about numerous different colours having different wavelengths.
The violet colour is said to have the shortest form of wavelength whereas red colour is said to have the longest wavelength.
