Some questions on waves?

Question

What is the mass, volume, and energy of a photon?
What are some high energy waves? and low?
Does going from a higher energy level to lower energy level release or absorb energy?
How do quantum leaps relate to wavelengths?
Whats the difference between the speed of light, wavelenghs and spectra of the sun and a mercury vapor lamp

Answer 1

This is a physics question i think. Luckily my background is in physics.

Photon has no mass, it is a point particle so it has no volume, photons have a range of energies...dependent upon the frequency on the EM spectrum anwhere from radio wave energy to cosmic ray energy.

Some high energy waves are cosmic rays and gamma rays. Some low energy waves are radio waves and mircrowaves.

If electrons drop from a higher to lower energy level a photon will be realsed. The energy of the photon will be propotional to its frequency on the EM spectra. An electron will not go from low to higher energy unless it absorbs an electron of the correct frequency.


Quatum leaps are related to the quatum mechanical nature of the atom. Electrons that change energy states will not continuosly move down to another energy level. They will disapear at one energy level and reappear in a lower energy level. When leaping like that they will relase energy that is proptional to the photons frequency. The frequecy is inversly proportinal to the wavelength.

There is no differnce between lamp and sun

There ya go. Good luck on the homework
