## Homework Statement

A transmitter sends out 1.8x10^7 waves per minute and generates a standing wave pattern. The radio waves travel at the speed of light to a receiver 20.0km away. Determine :

a) the frequency in herts

b) period

c)wave length

d) the time for one crest to travel from the transmitter to the receiver.

e) the number of nodes between the transmitter and the receiver.

## Homework Equations

F=1/t t=period, f=frequency

V=f x (wavelength)

## The Attempt at a Solution

i found b first by

60 seconds/ 1.8 x 10 ^7

=3.3 x 10^-6

a) 1/3.3 x 10^-6

=300,000 herts

im confused after this can someone help me please? thankyou
