Question

Calculate the (i) wave number and (ii)frequency of yellow radiation having wavelength 500A.​

Answer 1

Answer:

Calculate of wavenumber (v¯)

λ=5800A∘=5800×10−8cm=5800×10−10m

v¯=1λ=15800×10−10m=1.724×106m−1

=1.724×104cm−1

(b) Calculation of the frequency (V)

v=cλ=3×108ms−15800×10−10m=5.172×1014s−1
