Question

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

Answer 1

The correct option is A 36.6 m

$\lambda =\frac{c}{v}=\frac{3\times {10}^8}{8.2\times {10}^6}=36.5$ m
