The period of a 10 kHz radio wave traveling at 10\(^{8}\)...
The period of a 10 kHz radio wave traveling at 10\(^{8}\) ms\(^{-1}\) is--
3.0 x 10\(^{-5}\)s
1.0 x 10\(^{-4}\) s
1.0 x 10\(^{4}\)s
3.0 x 10\(^{4}\)s
Correct answer is B
The relation between period and frequency is that one is the inverse of the other.
By definition:
Frequency = 1/period.
or
period = 1/frequency → 1/ 10,000
period = 0.0001 or 1.0 x 10\(^{-4}\) s
