What are the wavelength ranges for the following?

(a) the AM radio band (540–1600 kHz)

maximum wavelength	______ m
minimum wavelength	______ m

(b) the the FM radio band (88–108 MHz)

maximum wavelength	______ m
minimum wavelength	_____ m

Expert Solution

formula wave length lamda=c/h

where c=speed of the light

= 3 * 10 ^ 8 m / s

a)

Maximum wavelength = ( 3 * 10 ^ 8 m / s ) / ( 540 * 10 ^3 Hz )

= 555.55 m

minimum wavelength = ( 3 * 10 ^ 8 m / s ) / ( 1600 * 10 ^ 3 Hz)

= 187.5 m

(b).

Maximum wavelength = ( 3 * 10 ^ 8 m / s ) / ( 88 * 10 ^ 6Hz )

= 3.409 m

Minimum wavelength = ( 3 * 10 ^ 8 m /.s ) / ( 108 * 10 ^6 Hz )

= 2.7777 m
