Unit 6- Light: Refraction vs Reflection STAAR Review

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

Why does a child's face appear smaller behind a jar of water?

Back

Because light travels in a straight line until it passes through water and is refracted.

Front

Which color of paint reflects more light?

Back

White paint reflects more light than black paint.

Front

What happens to light when it hits a mirror?

Back

Light travels in a straight line and reflects off the mirror.

Front

How does a periscope work?

Back

A periscope allows you to see objects that are not in your direct line of sight by using mirrors to reflect light at a 90-degree angle.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

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

Back

A concave mirror curves inward and can magnify images, while a convex mirror curves outward and can make images appear smaller.

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 hits a boundary at a steep angle and reflects completely back into the medium.
