To determine the correct formula for calculating the energy of a photon, let's go through some fundamental concepts in physics. Photons are elementary particles that represent quantum of light or other electromagnetic radiation. The energy of a photon is directly proportional to its frequency, and the relationship is captured by Planck’s equation.
In Planck’s equation:
- [tex]\( E \)[/tex] stands for the energy of the photon.
- [tex]\( h \)[/tex] represents Planck’s constant, which is a fundamental constant in quantum mechanics.
- [tex]\( f \)[/tex] denotes the frequency of the photon.
The correct formula relating energy [tex]\( E \)[/tex], Planck’s constant [tex]\( h \)[/tex], and frequency [tex]\( f \)[/tex] is expressed as:
[tex]\[ E = h f \][/tex]
None of the other given options correctly represent the relationship between energy, Planck’s constant, and frequency. Therefore, the accurate formula for calculating the energy of a photon is:
[tex]\[ E = h f \][/tex]
