Answer: \( E \approx 3.29 \times 10^{-19} \, \text{J} \)
Explanation: The energy of a photon can be calculated using the formula:
where:
- \( E \) is the energy of the photon,
- \( h \) is Planck’s constant (\( 6.626 \times 10^{-34} \, \text{J s} \)),
- \( c \) is the speed of light (\( 3.00 \times 10^8 \, \text{m/s} \)),
- \( \lambda \) is the wavelength in meters.
First, convert the wavelength from angstroms to meters:
Now, substitute the values into the energy formula:
Calculating this gives:
