Microwaves from a transmitter are directed normally toward a plane reflector. A detector moves along the normal to the reflector. Between positions of 14 successive maxima the detector travels a distance 0.14 m. The frequency of the transmitter is `(c = 3 xx 10^(8) m s^(-1))`.

A

`1.5 xx 10^(10)` Hz

B

`10^(10)` Hz

C

`3 xx 10^(10)` Hz

D

`6 xx 10^(10)` Hz

Text Solution

Verified by Experts

The correct Answer is:
A
`7lamda=0.14,lamda=0.02`
`f=(v)/(lamda)=(3xx10^(8))/(0.02)=1.5xx10^(10)Hz`
