Question
Microwaves from a transmitter are directed normally towards a plane reflector. A detector moves along the normal to the reflector. Between positions of 14 successive maxima, the detector travels a distance 0.14m. If the velocity of light is 3 × 108 m/s, find the frequency of the transmitter : -
Options
A.1.5 × 1010 Hz
B.1010 Hz
C.3 × 1010 Hz
D.6 × 1010 Hz
Solution
7λ = 0.14 ; λ = 0.02
f =
= 1.5 × 1010 Hz
f =
= 1.5 × 1010 HzCreate a free account to view solution
