Why does the beam of light change direction when it enters the water?
Because it slows down when entering water.
Does light change direction when it is absorbed by a material And if it does then how?
Yes if by absorbed, u mean go through, like water, then yes, it slows down and turns the direction of light
What direction does a plane mirror reflect light when the beam is aimed perpendicular to it?
Back up the indecent beam path.
Diverging mirrors on oil lamps on walls?
diverging mirrors behind oil lamps lets the light reflect all around the room instead of being reflected as one beam
Why are concave mirrors used in flood lights?
In flood lights,the source of light is placed between the pole and focus of a concave mirror so as to obtain a diverging beam of light..
When a light beam passes through a medium the beam can change direction and appear to bend and the process is called what?
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 .

Why car head lights have concave mirrors?
Because it collects and focuses as much as possible of the light from the bulb and send it out as a fairly tight beam in one direction only.
Does light change direction when it is absorbed by a material And if it does then how?
Yes if by absorbed, u mean go through, like water, then yes, it slows down and turns the direction of light
Why are concave mirrors used in reflectors and projectors?
Concave mirrors project a beam of light outward, which is what you want in a reflector or projector. This is also why they are used in vehicle headlight casing. It projects the beam of light further down the road so you can see better.
How does the laser works?
The laser works by reflecting and amplifying a beam of light through a tube of mirrors.
Where can the beam change direction in your eye?
In the eye lens
Light beam dimmer is chemical or physical change?
A beam of light becoming dimmer is a physical change since it is reversible. Recharging its source will make the light beam bright again.
What direction does a plane mirror reflect light when the beam is aimed perpendicular to it?
Back up the indecent beam path.
