<span>Here the force that is applied between the electron and proton is centripetal, so equate the two forces to determine the velocity.
We know charge of the electron which for both Q1 and Q2, e = 1.60 x 10^-19 C
The Coulombs Constant k = 9.0 x 10^9
Radius r = 0.053 x 10^-9m = 5.3 x 10^-11 m
Mass of the Electron = 9.11 x 10^-31
F = k x Q1 x Q2 / r^2 = m x v^2 / r(centripetal force)
ke^2 / r^2 = m x v^2 / r => v^2 = ke^2 / m x r
v^2 = ((1.60 x 10^-19)^2 x 9.0 x 10^9) / (9.11 x 10^-31 x 5.3 x 10^-11 )
v^2 = 4.77 x 10^12 = 2.18 x 10^6 m/s
Since one orbit is the distance,
one orbit = circumference = 2 x pi x r; distance s = v x t.
v x t = 2 x pi x r => t = (2 x 3.14 x 5.3 x 10^-11) / (2.18 x 10^6)
t = 33.3 x 10^-11 / 2.18 x 10^6 = 15.27 x 10^-17 s
Revolutions per sec = 1 / t = 1 / 15.27 x 10^-17 = 6.54 x 10^15 Hz</span>
Scientific evidence such as reflection and photoelectric effect has proven the wave-particle model of electromagnetic radiation to be true.
<h3>What is electromagnet radiation?</h3>
Electromagnetic radiation is radiation produced as a result of the interactions of the electric and magnetic fields.
Some forms of electromagnetic radiation include:
- radio waves
- microwaves
- ultraviolet radiation
- visible light
Electromagnetic radiation can be described using a wave model or a particle model.
The wave property of electromagnetic radiation include:
- diffraction
- reflection
- refraction
The particle property of electromagnetic radiation include:
- photoelectric effect
- Compton effect.
Therefore, the wave-particle model of electromagnetic radiation is correct because it can be backed up by experiments and evidence.
