>energy is proportional to the square of the frequceny
If we consider waves as particle performing SHM, then their energy
= 1/2m ω^2 A^2, where ω = 2πf
Can I use this concept in wave theory of light ?
hmm..I understand if I consider it per unit time, the intensity is directly proportional to the energy, not the frequecy.
My problem is that is the expression of "energy" include frequency ?
Like other waves, the particles are performing SHM, and their energy is proportional to the square of...
>You should cite this source. That is the one thing we try to make people do when they talk about something they read or heard.
oops, I read this from wikipedia.
let's forget about the light, what about other waves like sound and water ?
If we consider wave as the particles performing SHM...
For wave theory of light, it said that energy of light is depend only on its brightness and independent of its frequency.
I would like to ask which equation shows that wave energy is independent of frequency..??
thank you.
thank you for the explanation.
But how can the light for the light bulb becomes coherent after a single slit ?
How can the slit change their wavelength and frequency and make them the same ?
Laser emits due to the stimulated emission.
As the photons produce in this process are coherent, I would like to ask why they won't undergo interference and produce alternating bright and dark light when they just come out from the laser source.
thanks.
I would like to ask why a single slit is needed.
I have done some research and find that it makes sure the light goes to the double slits is coherent.
How can a single slits produce coherent light ?
and why the light comes from a natural source (e.g. lamp) is not coherent ?
In my...
