Question

2. Find the frequency of light that correspond to photons energy 5.0 x 10^-5 erg ?
​

Answer 1

Answer:

7.5 x10^21 sec -1

Explanation:

Using E=hv

we get

v=E/H=5.0 x10^-5 erg

____________

6.63 x10^-34Js

v= 5.0 x10^-5 erg

_____________

6.63x10^-34 x10 ^7erg sec

( 1J=10^7 erg)

v=7.54x10^21 sec^-1

Hope it helps
