When light passes into a glass block it changes direction what is the effect known as?

Light that approaches perpendicular to an interface between two different media (such as air and glass) *does not change direction*. Light that approaches such an interface at an angle other than 90° will change direction because the speed of light in the two different media is different. Simile: Think of a little red wagon running along a sidewalk, and one of its wheels drops off on the grass. The wheels on the sidewalk (like light through air) roll easily (like the speed of light in air), while the wheel in the grass (like light in glass) tends to want to roll more slowly for a given applied energy (like the lower speed of light in glass). The wagon will tend to suddenly turn fully out into the grass... (if it does not tip over and crash). it changes direction because the light is refracted.

∙ 11y agobeacuse it refracts
what is happening, physically, is that the speed of light in the glass block is different than the speed out in the air. When the wave hits, and this speed change causes the wave to be torqued into a new direction.
A physical situation similar to this would be driving a car down a road, one tire ont he pavement, the other on a really soft shoulder. That soft shoulder will act to slow down that side of the car. The faster side tries to get out ahead, but is instead turned (as it's still attached to the slow moving side) and the entire car is deflected off the road.

=======================
Answer #2:
There is refraction, and there is always some reflection.
Also, once the light is inside the glass, there is absorption.
Dispersion and scattering are likely in there as well, and if any
of the light comes out on the other side of the block, then
there is transmission.
The effect is known as refraction. Refraction occurs because light waves change speed when they pass from one medium to another, causing them to bend.

When light passes into the glass block it changes direction what is this effect known as?
This effect is known as refraction. Refraction occurs due to the change in speed of light as it travels from one medium to another, causing it to change direction.
When a light ray enters a glass block at an angle what happens to its direction?
The light ray changes direction as it enters the glass block due to refraction, where the speed of light changes as it passes from one medium to another. This change in direction is caused by the bending of the light ray towards the normal of the surface at the point of entry.
What happens when you shine a light at a glass block?
When light is shined at a glass block, some of the light is transmitted through the block, some is reflected, and some is absorbed. The transmitted light changes its direction due to refraction as it passes through the glass block.
Why does a stamp placed under a glass block appear raised?
When light enters or leaves one medium for another (in your case glass to air);the speed of the light changes - AND (unless absolutely perpendicular) its path of direction changes.What you see in your eye is the light from an object - not the object itself.The simplest example is a looking glass ... contemplate yourself.
Which way does the light change direction when it goes into the glass block?
Light changes direction when it goes into a glass block and exits out because it refracts due to the change in medium.
Which way does the light change direction when it goes into the glass block?
Light changes direction when it goes into a glass block and exits out because it refracts due to the change in medium.

What will happen to light rays if they do not enter a glass block?
If light rays do not enter a glass block, they will continue to travel in their original direction. The glass block will have no effect on the path of the light rays unless they actually enter the block.

What forces act on block and in which direction?
The main forces acting on a block are gravity (downward) and normal force (upward) from the surface it rests on. Additional forces may include friction when the block is in motion, tension if it is connected to a rope or string, and applied force if pushed or pulled by an external object.

How do racing car designers combat the effect of friction?
Racing car designers combat the effect of friction by using materials with low friction coefficients, such as lightweight and smooth materials for moving parts like bearings and gears. They also design aerodynamic features to reduce drag and improve airflow around the car, which can help minimize the effects of friction on speed and efficiency. Additionally, they may use lubricants and cooling systems to reduce heat buildup and friction between moving parts.

A block of glass that can split white light into different colors?
The block of glass is likely a prism. When white light passes through a prism, it is refracted (bent) at different angles based on its wavelength, causing it to separate into its component colors, creating a rainbow effect. This phenomena is known as dispersion.
