physics multiple question 2

Question

The best approximate wavelength range for radio and radar electromagnetic radiation is:

 

Question 5 options:

	104 → 10-2m
	10-1 → 10-4m
	10-3 → 7.5x10-7m
	7.5x10-7 → 4.0x10-7m
	4.0x10-7 → 10-9m
	10-9 → 10-12m
	10-11→10-16m
	10-16m and less

 

Answer 1

All types of Radio and RADAR waves have wave length band approximately above 1 meter.

Which is lies in First option ( 10⁴ → 10^-2 m).

So Option (1) → ( 10⁴ → 10^-2 m) is correct Answer.
