Light of wavelength

2000 \mathrm{~A}^{\circ}

falls on a plane reflecting surface. The wavelength of the reflected light will be

View answer and explanation

Correct option: D

2 \times 10^{-7} \mathrm{~m}

Option D is correct because the wavelength of light does not change upon reflection from a plane reflecting surface.
