Question

Find the wavelength of electromagnetic waves of frequency 5×10^19 Hz in free space. Give it's two application?

Answer 1

wave length = speed of light / frequency.
=> 3×10^8 / 5×10^-10-10^19

Answer 2

Answer:

Wavelength, λ= v/c

= 3×10^8 / 5×10^19 =6×10^ −12 m

These are gamma rays.

These are used for : (i) Nuclear reactions (ii) Radiotherapy.
