Question

The wave length of light is 500 angstrom express in

Answer 1

Answer:

500 angstorm = 5*10¹²metre.....

Answer 2

HOPE IT HELPS :

SINCE THE QUESTION IS NOT CLEAR :

Given , wavelength = 500 A OR $500 . 10^{-10} m$

Finding frequency of light :

c = wavelength x frequency

F = $(3 . 10^{8})/(500 . 10^{-10} )$

F = $(3 . 10^{16})/5$

F = $6 . 10^{15} Hz$
