Question 1

What is light?

Accepted Answer

Light is a form of energy that travels in waves. It's what lets us see everything around us.

Question 2

How does light travel?

Accepted Answer

Light travels in straight lines very fast, way faster than a car or airplane. It moves at a speed so quick, we can't even see it moving!

Question 3

Why do we need light to see?

Accepted Answer

We need light because it bounces off objects and into our eyes, helping us see them. Without light, everything would be dark and we couldn't see anything!

Question 4

What happens when light hits a mirror?

Accepted Answer

When light hits a mirror, it bounces back toward us. This is why we can see our reflection in mirrors.

Question 5

What makes a rainbow?

Accepted Answer

A rainbow happens when sunlight gets bent by raindrops in the sky. The light spreads out into different colors, making a beautiful arc in the sky.

Question 6

Why is the sky blue?

Accepted Answer

The sky is blue because the sunlight gets scattered in all directions by the air. Blue light scatters more than other colors, making the sky look blue to us.

Question 7

What are shadows?

Accepted Answer

Shadows are dark shapes made when something blocks light. They show the shape of the object that is stopping the light from passing through.

Question 8

How does light help plants grow?

Accepted Answer

Plants use light, especially sunlight, to make food in a process called photosynthesis. Without light, plants wouldn't be able to grow or survive.

Question 9

Can light go around corners?

Accepted Answer

Usually, light travels in straight lines, so it doesn't go around corners well. But, with mirrors or other surfaces, we can make it change direction.

Question 10

Why do things look bigger in water?

Accepted Answer

Things look bigger in water because light bends when it moves from air to water. This bending makes objects appear larger when we look at them through water.

Question 11

What are colors made of?

Accepted Answer

Colors are made by different wavelengths of light. Red, blue, and green mix together in different ways to make all the colors we see.

Question 12

Why do some objects glow in the dark?

Accepted Answer

Some objects glow in the dark because they absorb light and slowly release it over time. It's like storing light energy and then shining it out when it's dark!

Question 13

How do glasses help us see better?

Accepted Answer

Glasses help by bending the light correctly, so it focuses right onto the back of our eyes. This helps us see things clearly and not blurry.

Question 14

Why do stars twinkle?

Accepted Answer

Stars twinkle because their light passes through Earth's atmosphere, which makes the light bend in many directions. This makes stars appear to twinkle in the night sky.

Question 15

What does a prism do to light?

Accepted Answer

A prism splits white light into different colors by bending it. This is how we can see all the colors in white light.

Question 16

Can we see all kinds of light?

Accepted Answer

No, we can only see a small part of the light spectrum called visible light. There are other types like ultraviolet light that our eyes can't see.

Question 17

Why is a sunset red or orange?

Accepted Answer

Sunsets look red or orange because the sunlight passes through more air when it's lower in the sky. More blue light gets scattered, leaving reds and oranges for us to see.

Question 18

How does a camera capture photos?

Accepted Answer

A camera captures photos by letting light in through a lens onto a sensor or film. This records the image of whatever the light hits.

Question 19

What are rainbows on bubbles called?

Accepted Answer

The colorful patterns on bubbles are also rainbows, caused by light bouncing off the thin soap film. This makes beautiful swirling colors as the light bends.

Question 20

Why do we see lightning before we hear thunder?

Accepted Answer

We see lightning first because light travels faster than sound. So, the light from the lightning reaches us before the sound of the thunder.
