Question

A radio station broadcasts on afrequency of 103.7 MHz. What isthe energy of the radio wave?[?] × 10^[?] J

Answer 1

6.87 *10^-26 J

Explanation:

Given:

f = 103.7 MHz = 103.7 x 10^6 Hz

The energy of a radio wave is given by:

`\begin{gathered} E=hf \\ \\ \text{ h is the planck constant } \\ \\ \text{ We replacing:} \\ \\ E=(6.626\cdot10^(-34))(103.7\cdot10^6) \\ \\ E=6.87\cdot10^(-26) \end{gathered}`

the energy of the radio wave is 6.87 *10^-26 J
