Unit 5: Waves Assessment

Front

What is the definition of opaque?

Back

A material that does not allow light to pass through; it reflects or absorbs all light that strikes it.

Front

What does it mean for a material to be transparent?

Back

A material that allows light to pass through without significant scattering, enabling clear visibility.

Front

What is a translucent material?

Back

A material that allows some light to pass through but scatters it, making objects behind it appear blurry.

Front

What is reflection in terms of light?

Back

The bouncing back of light rays when they hit a surface.

Front

Define refraction.

Back

The bending of light as it passes from one medium to another due to a change in speed.

Front

What is absorption in the context of light?

Back

The process by which a material takes in light energy, preventing it from passing through or being reflected.

Front

What is diffraction?

Back

The bending of waves around obstacles and openings, which can cause spreading of waves.

Front

What is the fastest medium for light to travel through?

Back

A vacuum.

Front

What happens to light when it passes through a prism?

Back

It refracts and separates into different colors, demonstrating the spectrum.

Front

What is the principle of superposition in wave theory?

Back

When two or more waves overlap, the resulting wave is the sum of the individual waves.
