Question

If a source is transmitting an electromagnetic wave of frequency $8.2\times {10}^{6}Hz$, then the wavelength of the electromagnetic waves transmitted from the source will be:

• A. $36.6m$
• B. $40.5m$
• C. $42.3m$
• D. $50.9m$

Answer 1

The correct option is A $36.6m$

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