Question

Calculate wavenumber and frequency of yellow radiation having wavelength 5800a

Answer 1

Wave number is the reciprocal of wavelength

Wave number =1/5800 m-1

frequency =c/lemda
v=3×10^8/5800

Solve this with the help of calculator and you will get answer.

Good luck

Answer 2

Answer:

A.) 1.724 × 10⁴ cm‐1

B.) 5.172 × 10¹⁴ s-¹

Explanation:

A.) Calculation of wavenumber (v)

λ = 5800Å = 5800 × 10-⁸ cm

= 5800 × 10-¹⁰ m.

$v = \frac{1}{λ} = \frac{1}{5800 \times {10}^{ - 10}m }$

$= 1.724 \: \times {10}^{6} {m}^{ - 1}$

$= 1.724 \times {10}^{4} {cm}^{ - 1}$

B.) Calculation of The frequency (v)

$v = \frac{c}{λ} = \frac{3 \times {10}^{8} m {s}^{ - 1} }{5800 \times {10}^{ - 10}m } = 5.172 \times {10}^{14} {s}^{ - 1}$
