Question

uv light wave length is 150nm find wave number frequency of that light​

Answer 1

Explanation:

λ=150×10−9 m λ = 150 × 10 − 9 m . Now, we can compute the frequency as: f=cλ=3×108 m/s150×10−9 m=2.0×1015 Hz f = c λ = 3 × 10 8 m/s 150 × 10 − 9 m = 2.0 × 10 15 Hz .

Answer 2

Answer:

λ=150×10−9 m λ = 150 × 10 − 9 m . Now, we can compute the frequency as: f=cλ=3×108 m/s150×10−9 m=2.0×1015 Hz f = c λ = 3 × 10 8 m/s 150 × 10 − 9 m = 2.0 × 10 15 Hz .
