physics multiple choice

Question

The best approximate wavelength range for microwaves electromagnetic radiation is:

 

Question 3 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

The best approximate wavelength range for microwaves electromagnetic radiation is

1 mm = 1×10^-3 = 10^-3

Which is lies in second option ( 10^-1 → 10^-4 m).

So Option (2) → ( 10^-1 → 10^-4 m) is correct Answer.
