Radio waves have a velocity of 3 x 108ms-1. A radio station sends out a broadcast on a frequency of 800kHz. The wavelength of the broadcast is
-
A.
375.0m -
B.
267.0m -
C.
240.0m -
D.
37.5m -
E.
26.7m
Correct Answer: Option A
Explanation
v = F(lambda)
3 x 108 = (lambda) x 800 x 103
(lambda) = 375.0m
