Question

What is the energy of an electromagnetic wave with a electromagnetic wave with a frequency of 3 * 10 Hz ?

Answer 1

Answer:

$E=1.989*10^{-32}J$

Explanation:

From the question we are told that:

Frequency $f=3 * 10 Hz$

Generally the equation for Energy of an electromagnetic wave is mathematically given by

 $E=hf$

Where

  h=Planck's constant

  $h=6.62607015 * 10^{-34}$

Therefore

 $E=6.62607015 * 10^{-34}*3 * 10$

 $E=1.989*10^{-32}J$
