Explanation / Answer

Here ,

a) for the maximum wavelength for AM radio

maximum wavelength for AM = speed of em wave/(lowest frequency of wave)

maximum wavelength for AM = 3 *10^8/(540 *10^3)

maximum wavelength for AM = 555.6 m

b)

for the minimum wavelength for AM radio

minimum wavelength for AM = speed of em wave/(frequency of wave)

minimum wavelength for AM = 3 *10^8/(1600 *10^3)

minimum wavelength for AM = 187.5 m

c)

for the FM radio

maximum wavelength for FM = speed of em wave/(lowest frequency of FM)

maximum wavelength for FM = 3 *10^8/(88 *10^6)

maximum wavelength for FM = 3.41 m

d)

minimum wavelength for FM = speed of em wave/(lowest frequency of FM)

minimum wavelength for FM = 3 *10^8/(108 *10^6)

minimum wavelength for FM = 2.78 m
