rude man said:Do you think optics is important? Do you wear glasses or have ever used a pair of binoculars or looked thru a telescope or microscope? Do you like the looks of a rainbow?
Answer your question?
Refraction is the bending of light as it passes through different mediums, such as air, water, or glass. This bending is caused by the change in speed of light as it moves from one medium to another.
Refraction plays a crucial role in our daily lives, as it allows us to see objects that are not directly in our line of sight. It also helps in the functioning of various optical instruments, such as lenses in cameras and glasses.
The speed of light decreases as it passes through a denser medium, causing it to bend. This is because the particles in the medium absorb and re-emit the light, slowing it down.
Yes, refraction can be controlled by changing the angle at which light enters the medium or by using materials with different refractive indices. This is the principle behind lenses and prisms used in optical devices.
Refraction and reflection are both ways in which light can change direction. However, while refraction involves the bending of light, reflection is the bouncing of light off a surface without any change in direction.
