5.6C Light

Front

What is light reflection?

Back

Light reflection is the bouncing back of light rays when they hit a surface. This is how we see images in mirrors.

Front

What does it mean for light to be transmitted?

Back

Light transmission occurs when light passes through an object without being absorbed or reflected.

Front

Why can we see our reflection in a mirror?

Back

We can see our reflection in a mirror because the smooth surface of the mirror reflects a large amount of light.

Front

What is absorption of light?

Back

Absorption of light happens when an object takes in light rays, preventing them from being reflected or transmitted.

Front

What is refraction?

Back

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

Front

What is a hand lens used for?

Back

A hand lens is used to magnify small objects by bending light to make them appear larger.

Front

How does a periscope work?

Back

A periscope works by using mirrors to reflect light from an object, allowing us to see it from a different angle.

Front

What is a smooth surface's effect on light?

Back

A smooth surface reflects light more effectively, allowing us to see clear images.

Front

What happens to light when it hits a rough surface?

Back

When light hits a rough surface, it scatters in many directions, making images less clear.

Front

What is the role of mirrors in optical devices?

Back

Mirrors reflect light to create images, which is essential in devices like telescopes and periscopes.
