The correct option is (a) 635 nm.
What is a simple definition of a wavelength?
- A wavelength that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles.
- Wavelength is usually denoted by the Greek letter lambda (λ)
Given,
λ=6.36×10−7 m
Let C = the speed of light =3.00× [tex]10^{8}[/tex] m/s
Let f = the frequency = 4.72 × [tex]10^{14}[/tex] Hz
Let λ= the unknown wavelength
Now apply formula of wavelength
λ = C /f
λ = [tex]\frac{3.00 * 10^{8 }m/s }{4.72 * 10^{14} Hz}[/tex]
λ = 6.36 × [tex]10^{-7}[/tex] m
λ = 635 m
