Light travelling through wind?

Question

if,.... on a normal calm day, ligh travels through space at a 186,000 milesper sec,.... what formulas are used to detemine its speed on a windy day, and through a tornaodo.

(sorry about the spelling, but the keyboard is kaput.)L

Answer 1

Its a while since I did any sort physics, but as far as I can remember, Light is emitted as Photons, like particles of light, and these travel at light speed in a vacuum.

When light travels through materials it is slowed by the material. Same as if we were walking through air - quite fast - and then using the same energy walking through water - quite slow. The speed it slows is due to the resistance whch is a function of the photon size and its speed. I believe that there has been experiments where they actually stopped light (again, not sure if my memory is correct there, sorry).

So to answer your question, light is altered by the tornado,  however I am not sure of the formulas. I think the speed part of the equation is squared (the faster you go the more resistance), and the particle size is a constant but tats as far as I know

Answer 2

None,

The speed of light is constent and uninterupted untill it bounses of an objets and turns around. But other than that no stop or enething.

Answer 3

Sounds like you are trying to bring back the Michelson-Morley search for the ether.  Still won't find any.

The principle feature of AE's special theory of relativity is that the speed of light remains constant for all observers moving at constant velocity.  So, if you measured the speed on a calm day, you get one answer.  Now, get in a race car and go real fast (thru the air) and measure it again.  Same answer.  Now, put the car in park and crank up the tornado machine.  Same answer.

You can never make any conclusions about absolute movement by measuring the speed of light, since velocities are all just relative.

The speed does slow down some traveling thru air or any transparent material compared to a vacuum due to interaction with the medium.  That's the basis of refractive index.  What you can observe in the wind is the change in frequency as light reflects off objects moving relative to the source.  That's the basis for doppler radar.

Answer 4

the velocity will remain almost same.

it is more or less independent of these factors practically.

Answer 5

slightly differes..

speed of light depend on ratio of specific heat, universal gas constant and the temperature

Answer 6

I don't know but it seems logical that the speed would be the same.

Answer 7

Light does not travel, it is stationary and it is seen only in the theory  of Einstein ,which is completely and absolutely a wrong equation ,Light is seen only as long as it continue to give light it is seen by the naked eye
