Frequency help please

Question

Radio stations are usually identified by their frequency. One radio station in the middle of the FM band has a frequency of 96 MHz. What is its wavelength?

___m

What is the frequency of a microwave that has a wavelength of 3 cm?

____Hz

Answer 1

3.125 m and 90Hz

Answer 2

Lf = c; where L is wavelength, f is frequency, and c is light speed.

Solve for L = c/f; where f = 96E6 cycles/sec and c ~ 299E6 mps.

Solve for f = c/L; where L - .03 m and c as above.
