If a source is transmitting electromagnetic wave of frequency (8.2 10^6 ~Hz ), then wavelength of the electromagnetic waves transmitted from the source will be
Options
- A(36.5 ~m )
- B(40.5 ~m )
- C(42.3 ~m )
- D(50.9 ~m )
Correct answer
A. (36.5 ~m )
Step-by-step solution
Frequency of electromagnetic wave, (v=8.2 10^6 ~Hz ) Wavelength, ( = ) ? We know that, velocity of electromagnetic wave is given as ( aligned c & = v = c v & = 3 10^8 8.2 10^6 =36.5 ~m aligned )
