Given - λ (wavelength of green light) = 486nm
To find - the frequency of green light (f)
Solution -
The given problem can be solved using the following process that is as follow:
Let 'f' be the frequency of green light, 'c' be the speed of light and let 'λ' be the wavelength of green light.
As per the given condition,
λ = 486nm
λ
....(as the speed of the light is )
As we know, the speed of the given light is equal to frequency times its wavelength.
c = f × λ ...........(formula)
∴ f = c/λ ..........(rearranging the formula)
∴ By inserting the given values in the above-mentioned formula. we get,
.........(from given)
Hence, the frequency of the green light is 6.17* Hz
