Answer:
57.018*10^(-26)J

Energy is directly proportional to the frequency.

The energy of a photon is given by:

$E=h\\u$

Where, E is the energy and
$\\u$ is the frequency.

Frequency of the radio wave is given:

$\\u=8.6*10^8 Hz$

h=6.63*10^(-34)J.s

Multiply the above two:

Energy,

$E=h\\u=6.63*10^(-34)J.s*8.6*10^8 Hz= 57.018*10^(-26)J$

Hence, the energy of each photon of radio wave having frequency
$\\u=8.6*10^8 Hz$ is
57.018*10^(-26)J
