5.6C Reflection and Refraction

Front

What is Reflection?

Back

Reflection is the bouncing back of light when it hits a surface, allowing us to see images, like seeing ourselves in a mirror or a lake.

What is Refraction?

Back

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

What happens when light reflects off a smooth surface?

Back

When light reflects off a smooth surface, it creates a clear image, like a mirror.

What happens when light reflects off a rough surface?

Back

When light reflects off a rough surface, it scatters in many directions, making the image unclear.

Can you give an example of Refraction?

Back

An example of refraction is when a straw in a glass of water looks bent at the surface of the water.

What is the Law of Reflection?

Back

The Law of Reflection states that the angle of incidence is equal to the angle of reflection.

What is the angle of incidence?

Back

The angle of incidence is the angle between the incoming light ray and the normal (a line perpendicular to the surface).

How does a camera use Refraction?

Back

A camera uses refraction to focus light through its lens, allowing us to zoom in and out.

Front

What is a real-life example of Reflection?

Back

A real-life example of reflection is seeing your face in a calm lake or a still body of water.
