S8P4 - Waves Review

Front

What is a concave lens?

Back

A concave lens is a lens that is thinner in the center than at the edges and causes light waves to diverge.

Front

What is a convex lens?

Back

A convex lens is a lens that is thicker in the center than at the edges and causes light waves to converge.

Front

What happens to light when it passes through a concave lens?

Back

Light rays passing through a concave lens diverge, spreading out as they exit the lens.

Front

What happens to light when it passes through a convex lens?

Back

Light rays passing through a convex lens converge, coming together at a focal point.

Front

What is refraction?

Back

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

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface that does not absorb it.

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 a ray diagram?

Back

A ray diagram is a visual representation used to show the path of light rays as they interact with lenses and mirrors.

Front

What is the focal point of a lens?

Back

The focal point is the point where light rays converge or appear to diverge after passing through a lens.

Front

What is total internal reflection?

Back

Total internal reflection occurs when light hits a boundary at an angle greater than the critical angle, causing it to reflect entirely back into the medium.
