Light STAAR Review

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing objects to appear shifted or distorted.

Front

What does the objective lens of a telescope do?

Back

The objective lens refracts light to make distant objects appear closer.

Front

What happens to light when it enters water from air?

Back

Light is refracted as it moves from air to water, causing objects to appear closer to the surface.

Front

What is reflection?

Back

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

Front

How does light travel?

Back

Light travels in straight lines until it encounters a medium that changes its path.

Front

What is the role of a mirror in reflecting light?

Back

A mirror reflects light, allowing it to change direction based on the angle of incidence.

Front

What is the difference between reflection and refraction?

Back

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

Front

What causes a straw to look bent in a glass of water?

Back

The bending of light (refraction) as it moves from air to water makes the straw appear bent.

Front

What is the effect of light being blocked?

Back

When light is blocked, it creates a shadow in the area where the light cannot reach.

Front

What is an example of light being absorbed?

Back

When light hits a black surface, it is absorbed and converted to heat.
