Answer:
A. 5.71 × 10⁻²⁵ J
Explanation:
Energy of the photon can be calculated by using the formula:
[tex] \ \: E = h \nu [/tex]
where :
We have frequency = 8.63 × 10⁸ Hz.
substitute the values in the formula
[tex]E = 6.626 \times 10^{-34} Js \times 8.63 \times 10^8 Hz[/tex]
[tex]E = 57.1 \times 10^{-26}[/tex]
[tex]E = 5.71 \times 10^{-25} J[/tex]
Hence, the energy of the photon is A. 5.71 × 10⁻²⁵ J
The energy of a photon with a frequency of 8.63×10⁸ Hz is calculated using the equation E = hf. Using Planck's constant, the energy is found to be 5.71×10⁻²⁵ J, corresponding to option A.
To calculate the energy of a photon with a given frequency, we use the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.
Given the frequency of the photon as 8.63×10⁸ Hz and Planck's constant as 6.626×10⁻³⁴ J*s, we can calculate the energy of the photon as follows: E = (6.626×10⁻³⁴ J*s) × (8.63×10⁸ Hz) = 5.71×10⁻²⁵ J
Therefore, the correct answer for the energy of the photon is 5.71×10⁻²⁵ J, which corresponds to option A.
