which is the correct formula for finding the frequency of an electromagnetic wave?\no (f = c-lambda)\no (f=\frac{lambda}{c})\no (f=lambda + c)\no (f=\frac{c}{lambda})

which is the correct formula for finding the frequency of an electromagnetic wave?\no (f = c-lambda)\no (f=\frac{lambda}{c})\no (f=lambda + c)\no (f=\frac{c}{lambda})

Answer

Brief Explanations:

The relationship between the speed of light ($c$), wavelength ($\lambda$) and frequency ($f$) of an electromagnetic wave is $c = f\lambda$. Rearranging this formula for frequency gives $f=\frac{c}{\lambda}$.

Answer:

D. $f = \frac{c}{\lambda}$
