Explanation / Answer
1)Frequency: The number of instances in a specific phenemenon that exist in a stated span of duration is known as frequency. units are hertz i.e shortly hz.it is much unique in wirelesss communcations.

2) Wave length:The distance seated with single cycle of a wave.normally indicated in meters or feet.
..................................................................................................................................................................
3) generally relationship among thw wavelength and frquency i.e f= wavelength /velocity of light
= 3*10^8/40
=7500000
=7.5 MHZ
F =3*10^8/5
=60000000
= 60MHZ
f =3*10^8/(8*10^-2)
=3*10^8/0.08
=3750 MHZ
