The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters (e.g., 28 mm, 50 mm, or 100 mm). In the case of zoom lenses, both the minimum and maximum focal lengths are stated, for example 18–55 mm.
Answer:
it is long.
Explanation:
I know the answer but I don't know how to explain it
When an electron in a hydrogen atom transitions from the state of n=6 to n=1, a photon with an energy of 13.2 eV is released.
<h3>What components make up a photon?</h3>
- A photon is a microscopic particle that is part of electromagnetic radiation waves.
- Maxwell demonstrated that photons are merely electric fields flowing through space.
- A single photon can trigger a response from sensors in the retina.
<h3>What is the difference between an electron and a photon?</h3>
- Photons and electrons. One of the fundamental quantum-mechanical particles is an electron, although photons also exist and have entirely distinct properties.
- While the electron is a subatomic particle found in every atom, the photon is a sort of elementary particle that serves as an energy carrier.
