Yes, that is correct. The index of refraction of a material determines how much light will bend as it enters the material. A higher index of refraction means that the light will bend more as it enters the material.
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
Depends on the type of plastic.
The refractive index of a material signifies how much light slows down when it enters that material compared to its speed in a vacuum. It is a measure of how much the material can bend or refract light rays. Different materials have different refractive indices, which can impact how light interacts with them, such as causing light to be bent when passing through a lens.
It moves at a slower speed!
When light enters a new material, it may be absorbed, transmitted, or reflected depending on the properties of the material. Some of the light may also be refracted, which causes the light to change direction as it enters the new material. The speed of light may also change, which can lead to phenomena such as dispersion.
what happens when light enters a polorizing filter?
Yes, that is correct. The index of refraction of a material determines how much light will bend as it enters the material. A higher index of refraction means that the light will bend more as it enters the material.
When light moves from one material to another, it can be reflected, refracted, absorbed, or transmitted, depending on the properties of the materials involved. Refraction occurs when light changes speed and direction as it enters a new material, while reflection involves bouncing off the surface of the material. Absorption happens when the light is taken in by the material, and transmission occurs when light passes through the material without being absorbed.
An anisotropic material is a material which does not behave the same way in all directions. Take wood for example. Wood is very strong along the grain. Against the grain, however, it will easily break. The opposite of an anisotropic material is an isotropic material. Most metals (steel, aluminum) are isotropic materials. They respond the same way in all directions.
Pupils "constrict" when light enters, and "dilate "when the lighting dims
The light will bend away from the normal as it enters the material where its speed is higher. This bending of light is known as refraction. The amount of bending depends on the difference in the speed of light between the two materials.
some part of light reflected from the chair enters our eyes
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
When light enters a material of higher optical density, it will bend towards the normal. This deviation from the straight path is due to the change in speed of light as it travels from one medium to another.
