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.

The net force on the box parallel to the plane is
∑ F[para] = mg sin(24°) = ma
where mg is the weight of the box, so mg sin(24°) is the magnitude of the component of its weight acting parallel to the surface, and a is the box's acceleration.
Solve for a :
g sin(24°) = a ≈ 3.99 m/s²
The box starts at rest, so after 7.0 s it attains a speed of
(3.99 m/s²) (7.0 s) ≈ 28 m/s
Answer:
A) first laser
B) 0.08m
C) 0.64m
Explanation:
To find the position of the maximum you use the following formula:
m: order of the maximum
λ: wavelength
D: distance to the screen = 4.80m
d: distance between slits
A) for the first laser you use:
for the second laser:
hence, the first maximum of the first laser is closer to the central maximum.
B) The difference between the first maximum:
hence, the distance between the first maximum is 0.08m
C) you calculate the second maximum of laser 1:
and for the third minimum of laser 2:
Finally, you take the difference:
hence, the distance is 0.64m
