Q. If a source is transmitting electromagnetic wave of frequency $8.2 \times 10^{6}Hz$, then wavelength of the electromagnetic waves transmitted from the source will be
A) $36.6\ m$
B) $40.5\ m$
C) $42.3\ m$
D) $50.9\ m$
Explanation
(a) $\lambda = \frac{c}{v} = \frac{3 \times 10^{8}}{8.2 \times 10^{6}} = 36.5m$
