Question 1

What is light?

Accepted Answer

Light is a type of energy that lets us see things around us. It travels very fast and can come from things like the sun, light bulbs, and flashlights.

Question 2

Why is light important?

Accepted Answer

Light helps us see the world and all the colors in it. Without light, everything would be dark, and we wouldn't see anything at all.

Question 3

What are lenses?

Accepted Answer

Lenses are curved pieces of glass or plastic that can bend light. They help us see things more clearly or in a different way, like in glasses or cameras.

Question 4

How do lenses help us see better?

Accepted Answer

Lenses can bend light to focus it where we need it. This helps people with glasses see more clearly if their eyes need a little help.

Question 5

What is a rainbow?

Accepted Answer

A rainbow happens when light from the sun passes through raindrops and gets split into different colors. It looks like a colorful arc in the sky.

Question 6

How do cameras use lenses?

Accepted Answer

Cameras use lenses to focus light and capture clear pictures. The lens helps make sure the picture isn't blurry.

Question 7

Why are colors different?

Accepted Answer

Colors are different because they are made of light waves that have different lengths. Our eyes see these different wavelengths as different colors.

Question 8

What is reflection?

Accepted Answer

Reflection is when light bounces off an object. This is why we can see ourselves in mirrors; the light bounces back to our eyes.

Question 9

What is refraction?

Accepted Answer

Refraction happens when light bends as it passes through different materials, like water or glass. This is why a straw looks bent in a glass of water.

Question 10

How do glasses work?

Accepted Answer

Glasses have special lenses that help direct light into your eyes the right way. This helps people see clearly if their eyes can't do this on their own.

Question 11

What makes the sky blue?

Accepted Answer

The sky looks blue because sunlight gets scattered in all directions by the tiny particles in the air. Blue light is scattered more than other colors because it travels in shorter, smaller waves.

Question 12

How does a magnifying glass work?

Accepted Answer

A magnifying glass is a type of lens that makes things look bigger. It bends light to zoom in on what you're looking at.

Question 13

Why do things look smaller when they are far away?

Accepted Answer

When things are far away, less light reaches our eyes from them, and they look smaller. It's like they shrink the further they get from us.

Question 14

What is a prism?

Accepted Answer

A prism is a clear object, often made of glass, that splits white light into all the colors of the rainbow. It does this by bending the light.

Question 15

How does a telescope help us see stars?

Accepted Answer

A telescope has lenses and mirrors that gather more light than our eyes can. It lets us see stars and planets up close, even though they're really far away.

Question 16

What happens to light in a shadow?

Accepted Answer

A shadow forms when something blocks light from reaching a surface. The area behind the object doesn't get any light, so it looks dark.

Question 17

Why do some objects look shiny?

Accepted Answer

Shiny objects reflect light directly back at us. When light hits them, it bounces off smoothly, making them sparkle.

Question 18

What are sunglasses?

Accepted Answer

Sunglasses are glasses that help protect your eyes from bright light. They have special lenses that reduce the amount of light coming into your eyes, making sunshine less harsh.

Question 19

Can light go through everything?

Accepted Answer

Light can't go through everything. It can pass through clear things like glass but gets stopped by solid objects, like walls or books.

Question 20

What happens when you mix all the colors of light?

Accepted Answer

When you mix all the colors of light together, you get white light. This is why sunlight, which contains all colors, looks white to us.
