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) Here, $\lambda = \frac{c}{v} = \frac{3 \times 10^{8}}{8.2 \times 10^{6}} = 36.6\ m$
