What is the energy of an electromagnetic wave with a frequency of 8 x 10^12

omeli [17]

Answer:

Energy, $E=5.3\times 10^{-21}\ J$

Explanation:

It is required to find the energy of an electromagnetic wave with a frequency of $8\times 10^{12}\ Hz$ . The energy of a wave in terms of its frequency is given by :

$E=h\nu$

$\nu$ = frequency of em wave

$E=6.63\times 10^{-34}\times 8\times 10^{12}\\\\E=5.3\times 10^{-21}\ J$

So, the energy of an electromagnetic wave is $5.3\times 10^{-21}\ J$
