102.5 MHz (typical frequency for FM radio broadcasting) in joules

6.80×10¯²⁶ J

Explanation:

From the question given above, the following data were obtained:

Frequency (f) = 102.5 MHz

Energy (E) =?

Next, we shall convert 102.5 MHz to Hz. This can be obtained as follow:

1 MHz = 10⁶ Hz

Therefore,

102.5 MHz = 102.5 MHz × 10⁶ Hz / 1 MHz

102.5 MHz = 1.025×10⁸ Hz

Finally, we shall determine the energy. This can be obtained as follow:

Frequency (f) = 1.025×10⁸ Hz

Planck's constant (h) = 6.63×10¯³⁴ Js

Energy (E) =?

E = hf

E = 1.025×10⁸ × 6.63×10¯³⁴

E = 6.80×10¯²⁶ J
