**Question 12 of 65**

**What is the energy of a photon with a frequency of \(8.40 \times 10^{14} \, \text{s}^{-1}\)? (h = \(6.626 \times 10^{-34} \, \text{J} \cdot \text{s}\))**

This question asks you to calculate the energy of a photon given its frequency. The formula to use is:

\[ E = h \cdot f \]

Where:
- \( E \) is the energy of the photon.
- \( h \) is Planck's constant (\(6.626 \times 10^{-34} \, \text{J} \cdot \text{s}\)).
- \( f \) is the frequency of the photon (\(8.40 \times 10^{14} \, \text{s}^{-1}\)).

To solve the problem, multiply Planck’s constant by the frequency:

\[ E = (6.626 \times 10^{-34} \, \text{J} \cdot \text{s}) \times (8.40 \times 10^{14} \, \text{s}^{-1}) \]

Calculating this will give you the energy in joules.
