What is the reflection of light?

Reflection of light is when light rays change direction after encountering a surface or other boundary that does not absorb the energy of the radiation.

What is specular reflection?

Specular reflection is when light reflects off a polished surface, such as a mirror, perfectly reflecting any light bouncing off of it.

What is diffuse reflection?

Diffuse reflection is when light reflects from a rough surface, causing the light rays to scatter in different directions.

What is the law of reflection?

The law of reflection states that light reflects from a smooth surface at the same angle as it hits the surface. Signup and view all the answers

Why is reflection of light important?

Reflection of light is important because it is the basis for vision. People see objects because they either give off light or they reflect light from another source. Signup and view all the answers

What is the law of reflection?

The law of reflection states that when light reflects off a plane surface, the angle of incidence will be equal to the angle of reflection. Signup and view all the answers

What is specular reflection?

Specular reflection, or regular reflection, describes when light reflects off a polished, plane surface. Specular reflection obeys the law of reflection, the angle of incidence equals the angle of reflection. Signup and view all the answers

What is diffuse reflection?

When light is incident on a rough surface, it undergoes diffuse reflection. Each ray of light follows the law of reflection, but surface roughness causes the rays to be reflected at many different angles. Signup and view all the answers

What causes multiple reflections?

Multiple reflections occur when light reflects in two mirrors at an angle. The number of images formed depends on the angle between the mirrors. Signup and view all the answers

What is light reflection?

Light rays changing direction upon hitting a surface.
