5.8C Light PreTest

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air into water.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface, such as a mirror.

Front

What happens to light when it passes through a prism?

Back

Light is refracted, causing it to spread out into a spectrum of colors.

Front

What are opaque objects?

Back

Opaque objects do not allow any light to pass through them.

Front

What are translucent objects?

Back

Translucent objects allow some light to pass through, but not enough to see clearly through them.

Front

What are transparent objects?

Back

Transparent objects allow light to pass through them without scattering, making it possible to see clearly through them.

Front

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

Back

When light is absorbed, some of its energy is converted into heat energy.

Front

What is the main cause of a rainbow appearing?

Back

A rainbow appears due to the refraction, reflection, and dispersion of light in water droplets.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different mediums.

Front

Can light travel through all materials?

Back

No, light cannot travel through opaque materials.
