Question

Which physical quantity is same for all electromagnetic waves in free space

Answer 1

Explanation:

We know that speed is a physical quantity since it can be measured. Thus, the physical quantity which remains the same for microwaves of wavelength 1mm and UV radiations of 1600Ao in vacuum is velocity or speed of propagation.

Answer 2

Answer:

Thus, the physical quantity which remains the same for microwaves of wavelength 1mm and UV radiations of 1600Ao in vacuum is velocity or speed of propagation. Additional Information: Electromagnetic waves or EM waves are waves that have the contribution of both electric and magnetic fields.
