Question

Calculate the wavelength and frequency of yellow radiation having wavelength 5800a

Answer 1

v=f x lemda.

f=v/lemda

 frequency= 3.0x10⁸/5800=5.17x10⁵ Hz

wavelength = 5800 Angstrom..  =580nano metre

Answer 2

Answer:    

  ν = 5.17 × 10¹⁴ s⁻¹          

     V = 1.724 × 10⁶

Explanation:

Wavelength = 5800 A° = 5800× 10⁻¹⁰m - λ

speed of light = 3 × 10⁸ m/s - c

frequency - ν

wave number - V

Speed of light = wavelength × frequency

c = λν

ν = c / λ

ν = 3 × 10⁸ / 5800× 10⁻¹⁰

ν = 5.17 × 10¹⁴ s⁻¹

wave number - V = 1 / λ

                             = 1 / 5800 × 10⁻¹⁰

                             = 0.0001315 × 10¹⁰

                              = 1.724 × 10⁶
