Question

Microwaves have frequencies in the range 10^9to 10^12/s (cycles per second) equivalent to between 1 gigahertz and 1 terahertz. What is the wave length of microwave radiation whose frequency is 1.258 X 10^10/s?

How do I solve this problem

Answer 1

Worked the same as your next problem. The speed of light is 3E8 m/s

Answer 2

2.38×10^-2 m to 2.38×10^7 nm
