What is the name of the effect when light changes direction?
Reflection-when light change the direction of motion within same medium. Refraction-change of direction when moving to another medium.
Can the direction of a ray of light be changed?
Sure; mirrors, lens, prism, change of medium.
What is refracted light?
The refraction of light is the change in direction of a light ray when it crosses a boundary between two transparent substances. Refraction of light is the change in direction of a light ray due to a change in its speed as it goes from one medium to another.The speed and wavelength of a light ray change when this occurs, but the frequency remains the same.When light travels from denser medium to rarer medium it moves away from the normal [line at right angles to the boundary] and when light travels from rarer to denser it moves towards the normal.
When light enters a medium with a different refractive index they change speed or direction?
yes , if the light travel from less density to more density the speed will decrease , the direction will change depend on the entered angle
What is the refractive index of a substance?
It is the extent of the change in the direction of light as it passes from one transparent medium to another.
What determines the direction of energy transfer in a phase change?
light is form of energy then light is reflected at boundary of rarer medium and denser medium reflected ray is phase change of 180 degree's energy is phase changed direction of energy is opposite of transfer ed way
What does light do when it enters a medium?
refraction occurs if the medium is water. or it bounces of a solid,my guess :D
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 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 occors when light changes speed as it passes from one medium to another?
If the light is at an angle to the medium, then refraction (change of direction) and possibly reflection. If light travels at 90 degrees than maybe only slight reflection.
Why the light wave entering the second medium show no change in direction?
I can't see the setup of your experiment, so there's no way I could know why that happened in your case. But I can think of two possibilities where that would happen: 1). The light wave would not change direction if the refractive index of both media is the same number, regardless of what direction it approaches the boundary from. 2). The light wave would not change direction if it approaches perpendicular to the boundary, regardless of the refractive index of either medium.
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.
