When light goes out of a torch while moving into another light source

[newtwoophysic]

what happens specifically?

Could you rephrase please? That doesn't make any sense to me.

Can you really be far even as decided half as much to use go light for that? I think that when one really been far even as decided once the torch even go want, it is then that it has really been far even as decided to use even go want to do look more like.

Perhaps you have a friend who could translate for you? The above is completely indecipherable.


(I wonder if, based on the title, what he's asking is: if light comes out of a flashlight and impinges on light coming out of another flashlight, aren't they moving at 2c wrt to each other?)

When light from a torch moves into another light source, it undergoes a phenomenon called interference. This occurs when two or more light waves overlap and combine, resulting in either constructive interference or destructive interference.

Constructive interference is when the two light waves are in phase, meaning they have the same wavelength and are aligned in a way that their peaks and troughs line up. This results in an increase in the intensity or brightness of the light.

On the other hand, destructive interference is when the two light waves are out of phase, meaning they have opposite wavelengths and their peaks and troughs do not align. This results in a decrease in the intensity or brightness of the light.

In the case of a torch moving into another light source, the light waves from both sources will overlap and interfere with each other. Depending on their relative position and alignment, the resulting interference can either increase or decrease the overall brightness of the light.

Additionally, the color of the light may also change due to interference. This is because different colors of light have different wavelengths, and when they overlap and interfere, the resulting combined wave may have a different wavelength and therefore a different color.

Overall, the specific outcome of light moving into another light source depends on the properties of the two light sources and the resulting interference between their waves.
