Answer:
6.80×10¯²⁶ J
Step-by-step 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
