QUESTION:
Problem 27P
(I) What is the range of wavelengths for (a) FM radio (88MHzto 108 MHz) and (b) AM radio (535 KHz to 1700 KHz)?
ANSWER:
Solution 27P
Speed of light = 3*108 m/s
Wavelength = c/f where c is speed of light and f is frequency
Step 1 of 2
- FM radio
1 = 3*108 m/s / 88 * 106 Hz = 3.41 m
2 = 3*108 m/s / 108 * 106 Hz = 2.78 m
So wavelength range for FM radio is 2.78 - 3.41 m
