Is it true that when light passes from air to glass the light may change direction due to reflection?

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.

When light passes from air to glass the light may change direction due to reflection?
yes .. at any interface when light passes from one medium to another part of it gets reflected and remaining refracted. so some amount of light incident when passing from air to glass gets reflected. but in the reverse way i.e, from glass to air there is chance for all the light incident to get reflected as in the case of total internal reflection. and again coming to your case the amount of light reflected follows the laws of reflection i.e, angle of incidence is equal to the angle of reflection. the light which got refracted follows the snell's laws of refraction.
What happens when light passes from three different mediums like water to glass and glass to air?
In that case, it will change direction twice - in this example, once when it changes over from water to glass, and once when it changes from glass to air.
If a light mean travels through the air then through a glass container and finally through some water inside the container it might change directions how many times?
Light changes direction each time it passes from one medium to another - from air to glass, from glass to water, from water to glass, from glass to air. It will only NOT change direction if it is passing from one medium to another at exactly 90 degrees.
What do you call the change in direction of a wave at a boundary?
The terminology is the same for all waves, including light - so reflection or refraction depending on what you mean by change of direction. Firstly thanks for answering, I meant if you had water waves travelling from deeper to shallower water. The wavefront change direction when entering the shallower. so http://wiki.answers.com/Q/What_do_you_call_the_change_in_direction_of_a_wave_at_a_boundary" The effect is the same as bending of light as it goes from air into glass, for instance, it is refraction.
Which way does light change direction when it comes out of a block of glass?
out wards
What causes the change in direction when light passes into glass?
REFRACTION
When light passes at an angle from air to glass do the light changes direction due to refraction?
yes light changes its direction when it passes form air to glass due to refraction of light coz air has less density n glass is a solid so it has more density due to that when light goes form air to glass then its speed decreases n its always bends towords the normal. but if light will go perpendicularly form air to glass then it will not change its direction.

When light enters glass from air it changes direction. What is the change of direction called?
If the light is entering from air or a vacuum, the light will slow down. The affect of this, if the light hits the glass at an angle, is that the direction of the light will change.

How can light change direction?
There are various ways to change the direction of light. As a simple example, a mirror changes the direction of light by reflection. When light passes from one medium to another, such as from air to water it changes direction buy a process called refraction. Lenses, camera, telescope, microscope, spectacles, etc. use refraction to change the direction light as it passes from air into glass. A prism bends light is such that the various colors in light are bent different amounts and thus you can see them separately. The atmosphere bends light rays to create rainbows.A less widely known way light can caused to change direction is by the force of gravity. When light from a star passes close to a massive object in space such as a sun or giant planet or a black hole the gravity of the object pulls on the light changing its direction. This is a primary method of locating black holes -- they exert such tremendous gravitational pull light cannot escape from them (thus they are black and we can't see them), but when light from a star passes near them (but not to near) the bending of the light is a telltale of the black hole.Lenses, camera, telescope, microscope, spectacles, etc. use refraction to change the direction light as it passes from air into glass.

Why does the ray not change direction when it enters the glass at A?
sublimation
When light travels from air into a glass slab there is no change in its?
direction
When light speeds up does it change direction?
The only way light can speed up is if it passes from a more-optically-dense medium to a less-optically-dense one, like from glass into air, or from air into vacuum. When that happens, if the light doesn't hit the boundary in the direction that's perpendicular to it, then the light will change direction. That's how lenses work.
