Question 1

What is light?

Accepted Answer

Light is a type of energy that helps us see things around us. It's what comes from the sun, light bulbs, and flashlights.

Question 2

How does light travel?

Accepted Answer

Light travels in straight lines. It's very fast and can move around the world many times in just one second.

Question 3

Why is the sky blue?

Accepted Answer

The sky looks blue because of sunlight hitting tiny air particles. Blue light gets scattered in all directions, which makes the sky look blue to us.

Question 4

What is a rainbow?

Accepted Answer

A rainbow happens when sunlight shines through raindrops. The light bends and breaks up into all the colors we see.

Question 5

Why do objects have shadows?

Accepted Answer

Shadows form when something blocks light. The light can't go through the object, so it creates a dark spot behind it.

Question 6

What are colors?

Accepted Answer

Colors are how we see different kinds of light. The sunlight is made of many colors mixed together, but when they split, we see red, blue, green, and more.

Question 7

How do mirrors work?

Accepted Answer

Mirrors reflect light, just like bouncing a ball off a wall. When light hits a mirror, it bounces back so we can see our reflection.

Question 8

Why can we see our reflection in water?

Accepted Answer

Water can also work like a mirror. When light hits the surface of still water, it reflects back, showing us our reflection.

Question 9

What is a prism?

Accepted Answer

A prism is a glass or plastic shape that bends light. When light goes through a prism, it splits into all the colors of the rainbow.

Question 10

How do glasses help people see better?

Accepted Answer

Glasses have lenses that change the way light enters our eyes. This helps focus light correctly so everything looks clear.

Question 11

Why does the moon look bright at night?

Accepted Answer

The moon looks bright because it reflects light from the sun. Even though the moon itself doesn't glow, it shines because of the sunlight it reflects.

Question 12

What are UV rays?

Accepted Answer

UV rays are a kind of invisible light from the sun. They're not good for our skin, so we wear sunscreen to protect against them.

Question 13

What is a telescope?

Accepted Answer

A telescope is a tool to see things that are far away, like stars and planets. It gathers more light than our eyes can, making distant objects look closer and clearer.

Question 14

What is refraction?

Accepted Answer

Refraction is when light bends as it passes through something like water or glass. This bending can make things look bent or broken when seen through water.

Question 15

How does a camera capture a picture?

Accepted Answer

A camera uses a lens to focus light onto a surface called a sensor. The sensor captures the light and turns it into a picture we can see.

Question 16

Why do some objects glow in the dark?

Accepted Answer

Some objects can absorb light and then give off light slowly. This makes them appear to glow when it's dark.

Question 17

What is a laser?

Accepted Answer

A laser is a special kind of light that is very focused and powerful. Unlike normal light, a laser light doesn't spread out much, which makes it useful for cutting and other tasks.

Question 18

Why do stars twinkle?

Accepted Answer

Stars twinkle because their light has to pass through the Earth's atmosphere. The air moves the light around, making it look like the star is twinkling.

Question 19

What is the speed of light?

Accepted Answer

The speed of light is super fast, about 670 million miles per hour. It's the fastest thing we know of in the universe.

Question 20

How does a magnifying glass work?

Accepted Answer

A magnifying glass uses a curved lens to make objects look bigger. It bends light to focus more on a small area, so we can see details better.
