Question 1

What is a photon?

Accepted Answer

A photon is a tiny little packet of light. It's like a small ball of energy that travels really fast.

Question 2

How do we see light?

Accepted Answer

We see light when photons hit our eyes. Our eyes use the light to send messages to our brain, and that's how we see things!

Question 3

Why is the sky blue?

Accepted Answer

The sky looks blue because the photons from the sun scatter in the air. Blue photons scatter the most, so that's what we see!

Question 4

How does light travel?

Accepted Answer

Light travels in straight lines and moves super fast. It can go from the sun to Earth in about 8 minutes!

Question 5

Why do we need light?

Accepted Answer

We need light to see! Light helps plants grow, and it warms up the Earth, so it's pretty important.

Question 6

Can we see all kinds of light?

Accepted Answer

No, we can't see all types of light. We can only see a small part called visible light, which is the colors of the rainbow.

Question 7

What happens when light hits a mirror?

Accepted Answer

When light hits a mirror, it bounces back off. That's why we can see our reflection in a mirror.

Question 8

Why do objects have different colors?

Accepted Answer

Objects have different colors because they absorb some photons and reflect others. The color we see is the light that bounces back to us.

Question 9

What makes shadows?

Accepted Answer

Shadows happen when something blocks the light. The shape of the shadow depends on the shape of the object and where the light source is.

Question 10

How does light help plants?

Accepted Answer

Light helps plants by giving them energy to make food. Plants use light to turn water and air into food through a process called photosynthesis.

Question 11

Can light bend?

Accepted Answer

Yes, light can bend. When light goes through things like water or glass, it bends, and that's why things look different underwater.

Question 12

Why do rainbows form?

Accepted Answer

Rainbows form when light bends and scatters through water drops in the sky. The bending makes the light spread out into the colors we see in a rainbow.

Question 13

What is light made of?

Accepted Answer

Light is made of photons, tiny packets of energy. These photons have no weight and travel really fast.

Question 14

Does light make things hot?

Accepted Answer

Yes, light can make things hot. When light hits something, the energy can make the object warmer.

Question 15

What are colors?

Accepted Answer

Colors are different types of light our eyes can see. Each color is a different type of photon with its own special energy.

Question 16

How do glasses help us see better?

Accepted Answer

Glasses help by bending light so it focuses right in our eyes. This helps people see things more clearly.

Question 17

Why do stars twinkle?

Accepted Answer

Stars twinkle because their light moves through the air before reaching us. The air makes the light move around and that's why they seem to twinkle.

Question 18

How is sunlight different from artificial light?

Accepted Answer

Sunlight is natural and comes from the sun, while artificial light is made by humans using electricity. Both help us see, but sunlight also gives us warmth and vitamin D.

Question 19

Can animals see different light than us?

Accepted Answer

Yes, some animals can see light that we can't. Bees, for example, can see ultraviolet light, which helps them find flowers.

Question 20

Why do things look bigger underwater?

Accepted Answer

Things look bigger underwater because light bends differently in water than in air. This bending makes objects appear closer and larger.
