![**Question:**
What is the energy in joules (J) of a photon with a frequency of 73.2 MHz?
**Explanation:**
To find the energy of a photon, you can use the formula:
\[ E = h \times f \]
where:
- \( E \) is the energy in joules,
- \( h \) is Planck's constant (\(6.626 \times 10^{-34} \, \text{J}\cdot\text{s}\)),
- \( f \) is the frequency in hertz (Hz).
Given that the frequency \( f \) is 73.2 MHz, you first need to convert this into hertz:
\[ 73.2 \, \text{MHz} = 73.2 \times 10^6 \, \text{Hz} \]
Substituting the values into the equation:
\[ E = 6.626 \times 10^{-34} \, \text{J}\cdot\text{s} \times 73.2 \times 10^6 \, \text{Hz} \]
