Question

the frequency od wave of light is 12 × 10^14. the wave no. associated with this light is
a)5×10^-7 b)4×10^8
c)2×10^-7 d)4×10^4​

Answer 1

Answer:

Explanation:

D

Solution :

Frequency v=12×1014s−1 and velocity of light c=3×1010cms−1 . We know that the wave number v¯=vc=12×10143×1010=4×104cm−1
