Question

The frequency of an electromagnetic radiation is 4*10¹⁴H z .calculate its wavelength in mm.To which part of electromagnetic spectrum does it belong​

Answer 1

Answer:

750nm and visible region of emr spectrum

Explanation:

frequency(v) = 4×10^14 Hz or s^-1

Now,

w.k.t speed of emr in vaccum(c) = wavelength×frequency

wavelength = c/v

= (3×10^8) / (4×10^15)

= 3/4 ×10^8-14

= 0.75 ×10^-6

= 750nm

750nm is red light of the visible region of

Electromagnetic spectrum.
