Question

calculate Frequency of a radiation with wave
length 480nm​

Answer 1

Explanation:

λ=480nm=480×10−9m       [∵1nm=10−9m]

c=3×108m/sec

Frequency, v=λc=480×10−9m3×108ms−1=6.25×1014s−1 =6.25×1014Hz.

Answer 2

Answer:

Solution

Given λ=480nm=480×10−9m [∵1nm=10−9m] ltb rgt c=3×10−8m/sec ltBrgt Frequency v=cλ=3×10−8ms−1480×10−9m=6.25×1014s−1

=6.25×1014Hz
