Question

one of the spectrum line of censius has wavelength 856 NM calculate frequency of light​

Answer 1

Answer:

Wavelength and frequency is related by

Wavelength× frequency=Speed of light

GIVEN:

wavelength= 856 nm= 856×10^-9 m

And we know that Speed of light = 3×10⁸ m/s

To be calculated:

Frequency.

ANSWER:

frequency= Speed of light/ wavelength

=(3×10⁸) /(856×10^-9 ) Hz

=3.5047×10¹⁴ Hz
