Question

If the frequency of an electromagnetic wave is 6.0 x 108 Hz, what is its wavelength?

With solution

Answer 1

Gives

Frequency (n)=$6\times10^8 Hz$

We know that

$v=n\lambda$

Where $v=c=3\times10^8m/sec$

$\lambda=\frac{v}{n}$

Put values

$\lambda=\frac{3\times10^8}{6\times10^8}$$meter$

$\lambda=0.5meter$
