Question

calculate frequency and wave number of radiation emitted by sodium lamp whose wavelength is 5800Å​

Answer 1

Explanation:

Wavelength of light =5800×10−10 m

frequency = wavelengthC

= 5800×10 −103×10 8

=0.05×10 16

wave no.is reciprocal of wavelength wave no. = wavelength1

=0.017×10 8 m −1
