Yes. The mathematical law involving the indicies of refraction n1 & n2 and the angles A1 & A2 as;
n1 Sin(A1) = n2 Sin(A2)
will work regardless of which way the light is traveling. Just associate the variables n & A with the correct medium.
reflection is when light its something like a mirror and refraction is light going through something solid that is not like a mirror when light falls on a surface and bounces back, it is reflection and when light is absorbed by the surface or passes through the surface but does not bounces back, it is refraction.
The direction to where the wind is going.
You can tell the direction a footprint is going by observing the shape of the footprint. The deeper part of the print with more defined edges is typically the front of the foot, indicating the direction of movement. Additionally, the alignment of the toes can also give clues about the direction the person was moving in.
They're identical. They represent the same phase transition, going opposite ways, as it were. You can think of it as the border between, say, California and Nevada; it's in the same place regardless of which direction you're going.
The answer is either "zero" or "non-existent", for a number of different reasons:-- From either pole, there is no such thing as 'east' or 'west'. Every direction fromthe north pole is south, and every direction from the south pole is north.From either the north or south pole, the other pole is about 12,440 miles away,in ANY direction.-- From any point on earth except the poles, if you keep going far enough southyou'll eventually reach the south pole, and if you keep going far enough northyou'll eventually reach the north pole.But from any point on earth except the poles, if you keep going far enough east or west,you'll eventually wind up back exactly where you started, but you'll never reach either pole.Weird, eh ?
Yes. The laws of refraction are laws of physics and as such remain constant, as long as the space between the media is constant.
A ray of light will change direction when going out of water, into the air. This is called "Refraction".A ray of light will change direction when going out of water, into the air.

The change in direction of a wave going from one medium to another is called refraction. This occurs because the wave changes speed as it enters a new medium, causing it to bend either towards or away from the normal line, depending on the angle of incidence.
Reflection happens only at the interface between two media, and two media with the same index of refraction act as if they were a single medium. Thus, at the interface between media with the same index of refraction, there is no reflection, and the ray keeps going straight. Continuing this line of thought, it is not surprising that we observe very little reflection at an interface between media with similar indices of refraction.
either one direction or Cher Lloyd
Either any of the awesome boys
If a wave of light is reflected by an opaque material, it changes direction. If it refracts (like light going from air into water), it can change direction. Also, gravity can bend light. For example, a black hole can trap light.
When a wave bends as it changes speed and direction when passing from one medium to another, it is called refraction. This phenomenon occurs due to the change in the wave's speed as it enters a medium with a different optical density.
Its rumored but not confirmed by either of them.
You're going for "mirage", but we're not comfortable with that description. It's not really the "image" that's caused by refraction. It's more the location or direction in which the image is seen that's caused by refraction.
Russia is north of Florida and can be reached by going either northeast or northwest.
