Formative #8 Reflection, Refraction, and Lenses Review

Front

What type of lens is a convex lens?

Back

A convex lens is a lens that is thicker in the center than at the edges, causing light rays to converge.

Front

What is absorption in the context of light?

Back

Absorption is the process by which light is absorbed by a material, converting light energy into other forms of energy, such as heat.

Front

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.

Front

What is scattering in relation to light?

Back

Scattering is the process by which light is redirected in multiple directions when it strikes small particles or irregularities in a medium.

Front

What is reflection?

Back

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

Front

What is the difference between a convex lens and a concave lens?

Back

A convex lens converges light rays, while a concave lens diverges light rays.

Front

What is the focal point of a lens?

Back

The focal point is the point where parallel rays of light either converge (in a convex lens) or appear to diverge from (in a concave lens).

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 total internal reflection?

Back

Total internal reflection occurs when light attempts to move from a denser medium to a less dense medium at an angle greater than the critical angle, causing it to be completely reflected back into the denser medium.

Front

What is the critical angle?

Back

The critical angle is the angle of incidence above which total internal reflection occurs.
