Question 1

What is light?

Accepted Answer

Light is a type of energy that helps us see the world around us. It's what makes things bright and colorful.

Question 2

How does light travel?

Accepted Answer

Light travels in waves, kind of like the waves you see on the ocean. These waves can travel super fast, faster than anything else!

Question 3

What are light waves?

Accepted Answer

Light waves are ripples of energy that move through space. They help carry light from the sun to Earth.

Question 4

Can light be a particle?

Accepted Answer

Yes, light can also act like little tiny particles called photons. These photons carry energy from one place to another.

Question 5

Why can we see colors?

Accepted Answer

We see colors because light waves come in different lengths. Our eyes can pick up on these different waves and that's how we see colors.

Question 6

What makes rainbows appear?

Accepted Answer

Rainbows happen when sunlight bends and spreads out through raindrops. This bending splits the light into all its different colors.

Question 7

Why does a pencil look bent in water?

Accepted Answer

A pencil looks bent in water because light slows down when it hits water, bending the light waves. This bending makes things look like they're in a different place.

Question 8

Why does the sky look blue?

Accepted Answer

The sky looks blue because sunlight hits air particles and scatters. The blue light waves scatter the most, making the sky look blue!

Question 9

Can light travel through walls?

Accepted Answer

No, light can't travel through solid walls because they block the light waves. That's why we can't see through walls.

Question 10

What happens when light hits a mirror?

Accepted Answer

When light hits a mirror, it bounces off. This bouncing is why we can see ourselves in mirrors.

Question 11

Is sunlight the same as light from a lamp?

Accepted Answer

Sunlight and lamp light both let us see, but they come from different sources. Sunlight comes from the sun, while lamp light comes from electricity.

Question 12

Why are shadows formed?

Accepted Answer

Shadows are made when something blocks light. Light travels in straight lines, so when it's blocked, you see a shadow.

Question 13

What are photons?

Accepted Answer

Photons are tiny particles of light that carry energy. They help light move from one place to another.

Question 14

Can we see all types of light?

Accepted Answer

No, we can't see all types of light. Some light waves are too short or too long for our eyes to see, like ultraviolet or infrared light.

Question 15

Why do glasses help us see better?

Accepted Answer

Glasses help focus light waves that enter our eyes, making things clearer. They bend light in just the right way so we can see better.

Question 16

What is a prism and what does it do?

Accepted Answer

A prism is a clear object that bends light. When light goes through a prism, it splits into a rainbow of colors.

Question 17

How do cameras use light to take pictures?

Accepted Answer

Cameras let light enter through a lens, focusing it to create pictures. The light makes an image on film or a digital sensor.

Question 18

Why do some materials look shiny?

Accepted Answer

Materials look shiny because they reflect a lot of light. The light bounces off their surface, making them sparkle.

Question 19

Why can't we see in the dark?

Accepted Answer

We can't see in the dark because there's no light for our eyes to detect. Our eyes need light waves to see anything.

Question 20

What is the speed of light?

Accepted Answer

The speed of light is super-fast, about 299,792 kilometers per second. It's the fastest thing in the universe!
