Want this question answered?
It is true that light will change direction when going from one medium to another (such as going through space to going through air. Further, different wavelengths of light (different colors) will change at different angles; this is why a prism works and why the sky is blue. However, this process is called refraction, not reflection.
Refraction
leave yourself an out
Light is refracted by a discontinuity in the refractive index of the medium ... by going from one medium into another one where the speed of light is different.
Acceleration is the change in velocity. Velocity is the change in speed or direction. Therefore, acceleration is changing the change in speed or direction. So if you are going at 50mph and then you are going at 55mph and then at 60mph, your acceleration is constant at 5 mph. if the change in accleartion is changing, then it is not constant. If you turn dirctions even while you move at a constant velocity, you are accelerating.

Once the light leaves the source, its frequency doesn't change, no matter what ittravels through or what kind of exciting adventure it encounters.But if it passes from one medium to another one with a different index ofrefraction, then the speed and wavelength change, and the direction of aray of light may change.

because they want to
As long as the speed doesn't change and the direction doesn't change, its acceleration is zero.
Refraction, which is the bending of light
Light is refracted by a discontinuity in the refractive index of the medium ... by going from one medium into another one where the speed of light is different.
Domestic and Foreign policy: they decided to change the direction they were going before by reducing or raising taxes.
Yes, Light bends towards the normal when it travels from air to another medium and bends away when going into air from another medium. This can be affected by the angle of incidence and what angle it is.
Walk up to the wheel and press e, you should see arrows going in the opposite direction if done correctly.
