Question 1

What is a photon?

Accepted Answer

A photon is a tiny particle of light. Think of it as a little packet of energy that travels from the sun to Earth, helping us see and making plants grow.

Question 2

How does light travel?

Accepted Answer

Light travels in straight lines at a super-fast speed. It moves so fast that it can go around the Earth seven and a half times in just one second!

Question 3

Why is light important?

Accepted Answer

Light is important because it lets us see the world around us. It also helps plants make food and keeps us warm by coming from the sun.

Question 4

Can we see all kinds of light?

Accepted Answer

No, we can only see a small part of light called visible light. There are other types, like ultraviolet and infrared, which our eyes can't see without special tools.

Question 5

Why does a rainbow have different colors?

Accepted Answer

A rainbow happens when light bends and splits into different colors. Each color bends a little differently, making them spread out into the rainbow we see.

Question 6

How do we use light in our everyday lives?

Accepted Answer

We use light to see, read, take pictures, and watch TV. Lights also guide us, like traffic lights, and help doctors see inside our bodies with x-rays.

Question 7

What happens to light when it hits a mirror?

Accepted Answer

When light hits a mirror, it bounces back, letting us see our reflection. This bouncing of light is called reflection.

Question 8

Why does the sun look yellow?

Accepted Answer

The sun looks yellow because Earth's atmosphere spreads out blue light more than red light. So, the remaining light that reaches our eyes is mostly yellow.

Question 9

What is a shadow?

Accepted Answer

A shadow is a dark shape that happens when something blocks the light. It's where the light can't reach because there's something in the way.

Question 10

How does light make plants grow?

Accepted Answer

Light helps plants make their food in a process called photosynthesis. Plants use sunlight to turn water and air into food, which helps them grow.

Question 11

Why do our eyes hurt if we look at the sun?

Accepted Answer

Looking at the sun can hurt our eyes because it's very bright and has a lot of energy. This bright light can damage the cells in our eyes.

Question 12

Why is the sky blue?

Accepted Answer

The sky looks blue because the Earth's atmosphere scatters the blue parts of sunlight in all directions. Blue light is scattered more than other colors because it travels in shorter, smaller waves.

Question 13

What happens when light goes through a prism?

Accepted Answer

When light goes through a prism, it bends and spreads out into all of its different colors. This is how you can see a mini rainbow!

Question 14

Can animals see different kinds of light that we can't see?

Accepted Answer

Yes, some animals can see light that humans cannot. For example, bees can see ultraviolet light, which helps them find flowers.

Question 15

Why do we use night lights?

Accepted Answer

We use night lights so we can see a little when it's dark without turning on all the bright lights. It helps us feel safe and find our way around at night.

Question 16

What is reflection?

Accepted Answer

Reflection is when light bounces off a surface, like a mirror or shiny water. This bouncing lets us see images or light up spaces.

Question 17

How do glasses help people see better?

Accepted Answer

Glasses help by bending the light so it focuses correctly in our eyes. This makes things look clear instead of blurry.

Question 18

What are lasers?

Accepted Answer

Lasers are special beams of light that are really straight and powerful. They can be used for cutting things or as pointers in presentations.

Question 19

Why do stars twinkle?

Accepted Answer

Stars twinkle because their light has to pass through the Earth's atmosphere. As the air moves, it bends the light in different ways, making the stars look like they're twinkling.

Question 20

How does light help us communicate?

Accepted Answer

Light helps us communicate through things like fiber optic cables, which send information as light signals. This is how we get fast internet and phone calls!
