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
Verified Correct Answer: A.
Physical Principles & Numerical Solution
v = F\(\lambda\)
3 x 108 = \(\lambda\) x 800 x 103
\(\lambda\) = 375.0m
