A plane electromagnetic wave of frequency 40 MHz travels in free space in the X-direction. At some point and at some instant, the electric field E has its maximum value of 750 N/C in Y-direction, the period of the wave will be: |
2.5 µs 0.25 µs 0.025 µs None of these |
0.025 µs |
T = $\frac{1}{f}=\frac{1}{4 \times 10^7}$ = 0.025 µs |
