The incident ray is the ray of light going towards the mirror. The reflected ray is the ray of light coming away from the mirror. The normal is a reference line drawn at right angles to the...
Aug 17, 2022 · The light waves reflected off boats or other objects strike a mirrored surface inside the periscope. This surface is placed at a slight angle so that the reflected rays can be sent down the tube of the periscope. The light ray enters at an angle of 45 o to the normal and will therefore be reflected off at an equal angle of 45 o. As the mirror ...
Light rays that reflect follow the law of reflection. The law of reflection states that the angle of reflection * is equal to the angle of incidence. Light rays that pass through an interface are transmitted rays. These rays bend. This bending is called refraction.
Light waves are refracted as they enter the glass because they are slowed down. The spectrum is produced because different colours of light travel at different speeds in glass.

The way light changes directions has to do with the properties of the material it is travelling through. Every material has a unique index of refraction. This measurement is identified using the letter n. The index of refraction of a material is equal to the speed of light in a vacuum, divided by the speed of light in the material. The higher the i...
We can make light go in different directions using lenses. A lensis an optical device made of plastic or glass. When light passes through a lens, it can be refracted in predictable directions. The directions depend on the shape of the surfaces of the lens.
Light entering a plastic or glass prism, refracts as it enters the prism and again as it exits the prism.
Nov 14, 2024 · The amount of bending of a light ray as it crosses a boundary between two media is dictated by the difference in the two indices of refraction. When light passes into a denser medium, the ray is bent toward the normal.
