Question 1

What is light?

Accepted Answer

Light is a kind of energy that helps us see everything around us. It's like an invisible wave that travels really fast.

Question 2

Why do we need light to see?

Accepted Answer

We need light because it bounces off objects and into our eyes, allowing us to see the colors and shapes of things.

Question 3

How does a lens work?

Accepted Answer

A lens bends light so we can see better. It's just like how a magnifying glass makes things look bigger by bending light.

Question 4

What are lenses made of?

Accepted Answer

Lenses are usually made of glass or plastic. They are shaped in a special way to bend light just right.

Question 5

Why do rainbows appear?

Accepted Answer

Rainbows appear when sunlight bends as it goes through water drops in the sky. The bending splits the light into different colors.

Question 6

What are colors?

Accepted Answer

Colors are what we see when light bounces off things and hits our eyes. Different objects reflect different colors from the light.

Question 7

How does light travel?

Accepted Answer

Light travels very fast, in straight lines, until it hits something. It can pass through clear things like air or glass.

Question 8

Why is the sky blue?

Accepted Answer

The sky is blue because the air spreads blue light from the sun all over. This makes the whole sky look blue to us.

Question 9

What is a shadow?

Accepted Answer

A shadow is a dark shape on the ground or wall when something blocks light. It shows the shape of the object that's in the way.

Question 10

How do our eyes see?

Accepted Answer

Eyes see by letting light in and sending a message to our brain, so we recognize what's around us. They're like tiny cameras.

Question 11

What happens when you look through a telescope?

Accepted Answer

When you look through a telescope, it makes far-away things like stars and planets look closer. This is because it uses lenses to bend light.

Question 12

Why do we wear glasses?

Accepted Answer

We wear glasses to help us see better. Glasses have special lenses that change how light enters our eyes.

Question 13

What is a prism?

Accepted Answer

A prism is a clear object that bends light, showing all its colors. It's shaped like a triangle, and it separates light into a rainbow.

Question 14

How does a camera use lenses?

Accepted Answer

A camera uses lenses to capture light and create pictures. The lens focuses light onto a film or sensor inside the camera.

Question 15

What is reflection?

Accepted Answer

Reflection is when light bounces off a surface, like a mirror. That's why you can see yourself in a mirror.

Question 16

Why can't we see in the dark?

Accepted Answer

We can't see in the dark because there is no light to bounce off objects and into our eyes. That's why we need lights at night.

Question 17

What makes light bend?

Accepted Answer

Light bends when it travels from one thing to another, like from air to water. This bending is called refraction.

Question 18

How does a microscope work?

Accepted Answer

A microscope uses lenses to make tiny things look bigger so we can see them. It's like a super strong magnifying glass.

Question 19

What are the colors in a rainbow?

Accepted Answer

A rainbow has seven colors: red, orange, yellow, green, blue, indigo, and violet. These colors appear when light is split and bent.

Question 20

What is the speed of light?

Accepted Answer

The speed of light is how fast light travels, and it's super quick! It's faster than anything else we know.
