Which characteristic is NOT attributed to photons?
Which characteristic is NOT attributed to photons?
- Having mass (correct)
- Possessing discrete packets of energy
- Being fundamental particles
- Composing electromagnetic radiation
What distinguishes photons from other fundamental particles, such as electrons or quarks?
What distinguishes photons from other fundamental particles, such as electrons or quarks?
- Photons are not fundamental particles, unlike electrons and quarks.
- Photons are only found in specific types of matter, while electrons and quarks are ubiquitous.
- Photons possess an electric charge, while electrons and quarks are neutral.
- Photons are massless, while electrons and quarks have mass. (correct)
If a photon's energy increases, what happens to its frequency, assuming its fundamental properties remain unchanged?
If a photon's energy increases, what happens to its frequency, assuming its fundamental properties remain unchanged?
- It increases proportionally. (correct)
- It remains the same.
- It decreases proportionally.
- The change in frequency depends on the medium through which it travels.
