Which way does light change direction when it comes out of a block of glass?
out wards
Why does light change direction in a glass block?
It doesn't it it hits it straight on. But - Light slows down when passing through glass (as compared to air), so think of a light beam as a bunch of soldiers walking side by side. If the ones at on one end of the line slow down then their path will bend.
What happens to a ray of light as it enters and leaves a glass block?
The ray of light gets refracted. Depending on the medium it is entering, it will bend either to or away from the normal. For example, if it is entering a glass block from air, it will bend towards the normal, and if it leaves a glass block and enters air it will bend away from the normal. The amount the ray bends depends on the angle of incidences and the refractive indices of the two mediums, and are governed by Snell's Law.
What is the main principal of lens?
Lenses are based on refraction - the change of direction of rays of light, when they change from one medium to another, such as from air to glass.
What happens to some of the light before entering a glass block?
When light enters a glass block, it undergoes reflection and refraction. However at the glass air interface, refraction occurs to a larger extent than refraction and hence some of the light is reflected while the rest of it enters the glass block.

What happens when you shine light through a glass cuboid?
This will depend on the angle of incidence. If the light source is perpendicular to the edge of the the block then it will pass through with no change in direction. However if the light source is not perpendicular then the light will alter in direction slightly due to the change in speed of the light waves (light travels slower through the block than the air). When leaving the block the light will resume its original trajectory but slightly offset (parallel to the original beam).
When light travels from air into a glass slab there is no change in its?
direction
What causes the change in direction when light passes into glass?
REFRACTION
What happens to the direction of a light ray as it travels from glass into the air?
the light 'beam' (if you like) will slightly change direction this is bending light, light only travels in straight lines but due to the shape of the glass it changes direction when the beam exits the glass its should go back to its shape of ligh beam .

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.

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 at an olique angle the wave crests change direction there new direction is what?
The angel of the light ray emerging is called "Angle of Deviation"
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend if it enters a glass block perpendicularly.
Does light bend at the surface or middle of a block of glass?
bend at surface and continued in the same direction in bulk of it...and again bend at emerging surface.........
