Why does a pencil appear broken at the boundery between air nd water of the glass and water as viewed at the side of a glass of water?
Your eye is interpreting the path taken by the light that reflects off the pencil.
Why do a pencil appear to be bent or broken when seen through the side of the glass?
Because of refraction of light
When you are standing in front of a windowpane made of glass we can see through it and at the same time we can also see our image in it why?
Because when light encounters the surface of a windowpane made of glass, a portion of the light energy reflects from the glass surface and returns whence it came, and the remainder of the light energy proceeds through the glass.
What happens when a person looks at a glass of water with a pencil in it?
As light hits the water it is slowed down. As the light above the water is going at 3x108 m/s, and the light in the water is going considerably slower, the image of the pencil looks like it is split in two. This is called 'refraction'.
Why does light bend when it goes through glass at an angle?
Change in speed of the light in glass. Fermat showed that time is invariant in light paths. This results in Light following the Law of Signs. sin(Air Angle)/speed in air = sin( Glass Angle)/speed in glass .
How do the light waves coming from the pencil change speeds?
when the pencil enters the water
Where do the light waves change speed from a pencil?
ACTUALLY ! Its when the pencil enters the water .
What happens when light is refracted through glass?
The light will bend into an angle because of the shape of the glass and the location from which the light is coming from.
Why did the light bulb change brightness along the pencil?
because the pencil take the a litte enrgy.
When a ray of light from air enters to glass what happens to wavelength?
It will not change. Glass slows light but does not change it frequency.

Red triangle light keeps coming on in your car what is it?
i think it is glass
Is sun coming in a window direct light or indirect?
Light coming through unfiltered/untinted glass is Direct sunlight. Light coming through shade/screen/curtains, etc, is Indirect.
What is rare faction examples?
One example of refraction of light is a rainbow and a broken pencil when placed in a glass of water.
What happens when a ray of light falls on a pencil kept in the tumbler filled with water?
Nothing happens when the ray of light hits the pencil. But it bends when it crosses the boundary between the air and the water. Your brain ... thinking that the end of the pencil is in the same direction that the ray of light is coming from ... thinks that the part of the pencil under the water is in a place where it's not, so the pencil appears bent at the water line.
The colour of light which travels through glass with the minimum speed is?
Light does not change speed when it goes through glass.
