Question

calculate wavelength, wave no.and frequency of a photonof an electromagnetic radiation having wavelength 7600Ao​

Answer 1

Answer:

         ν = 3.94 × 10¹⁴ s⁻¹

                 V = 1.315 × 10⁶

Explanation:

Wavelength = 7600 A° = 7600× 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 / 7600× 10⁻¹⁰

ν = 3.94 × 10¹⁴ s⁻¹

wave number - V = 1 / λ

                             = 1 / 7600 × 10⁻¹⁰

                             = 0.0001315 × 10¹⁰

                            = 1.315 × 10⁶
