What are some equations that require the mass of an electron? I'm sure there are thousands, but none spring to mind... Also, is it fair to say that electron mass is an essential quantity in quantum physics?
I do not have equations to hand but areas where electron mass is required include design of electron guns, CRTs and magnetrons, transit time effects in a vacuum tube and magneto ionic resonance in the ionosphere.whatisreality said:What are some equations that require the mass of an electron?

The equation for calculating the mass of an electron is m = √(h^2 / (4π^2 * r^2 * v^2)), where m is the mass, h is Planck's constant, r is the radius of the electron's orbit, and v is the velocity of the electron.
Quantum physics explains the mass of an electron by treating it as a wave-particle duality. This means that the electron can behave as both a particle and a wave, and its mass is determined by its wave-like properties.
The mass of an electron is directly proportional to its charge. This means that when the charge of an electron changes, its mass will also change accordingly.
The mass of an electron is experimentally determined using various methods, such as mass spectrometry, cyclotron resonance, and the Millikan oil drop experiment. These methods involve measuring the electron's charge and its motion in an electric field to calculate its mass.
The mass of an electron is a fundamental constant and is not known to change. However, some theories in physics suggest that the mass of an electron may change under extreme conditions, such as near a black hole. This is an area of ongoing research and has yet to be fully understood.
