What is reflection in the context of light?

Back

Reflection is the bouncing back of light rays when they hit a surface that does not absorb the light.

What happens to light when it is absorbed by an object?

Back

When light is absorbed by an object, it is taken in by the material and converted into other forms of energy, such as heat.

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

How does a mirror change the direction of light?

Back

A mirror changes the direction of light by reflecting it off its surface, allowing the light to travel in a straight line after reflection.

What is the principle of light traveling in a straight line?

Back

Light travels in a straight line unless it interacts with an object, which can cause reflection, refraction, or absorption.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What is the angle of incidence?

Back

The angle of incidence is the angle between the incoming light ray and the normal (perpendicular) to the surface at the point of incidence.

What is the angle of reflection?

Back

The angle of reflection is the angle between the reflected light ray and the normal to the surface at the point of reflection.

What is a normal line in optics?

Back

A normal line is an imaginary line that is perpendicular to the surface at the point where the light ray strikes.

Front

What is the difference between reflection and refraction?

Back

Reflection involves light bouncing off a surface, while refraction involves light bending as it passes through different media.
