Question

light of wavelength 350nm falls on a plane reflecting surface what are wavelength and frequency of reflecting light in angstron and hertz​

Answer 1

wavelength of light is

$3500$

speed of light c is

$c = 3 \times {10}^{8}$

frequency is

$γ= \frac{c}{λ}$

$γ= \frac{3 \times {10}^{8} }{3500}$

$γ= 0.85 \times {10}^{5} hz$

hope this helps.❤
