Question

Calculate (a) wavenumber and (b)
frequency of yellow radiation having
wavelength 5800 Å.​

Answer 1

Answer:

Explanation:

Wave number = 1/Wavelength  

                        = 1/(5800 * 10⁻¹⁰ m)

                        = 1.724 × 10⁶ m⁻¹

Frequency = velocity of light / Wavelength  

                  = 3 × 10⁸ / (5800 × 10⁻¹⁰)

                  = 5.172 × 10¹⁴ Hz
