Question 1

What is light?

Accepted Answer

Light is a kind of energy that lets us see things. It travels as tiny particles called photons.

Question 2

What are photons?

Accepted Answer

Photons are tiny bits of light that move very fast. They help light travel from one place to another.

Question 3

How fast does light travel?

Accepted Answer

Light travels incredibly fast, at about 186,000 miles per second. That's like going around the Earth 7 times in one second!

Question 4

Why can we see things when there's light?

Accepted Answer

We can see things because light bounces off objects and enters our eyes. Our eyes then tell our brains what the objects look like.

Question 5

Why do some things glow in the dark?

Accepted Answer

Some things can store up light energy and let it out slowly, making them glow even when it's dark. This is called phosphorescence.

Question 6

Why is the sky blue?

Accepted Answer

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

Question 7

What makes a rainbow?

Accepted Answer

Rainbows happen when sunlight passes through raindrops. The light is bent and separated into different colors, making a rainbow in the sky.

Question 8

Can we see all kinds of light?

Accepted Answer

No, we can't see all kinds of light. We can only see visible light, but there are other kinds like ultraviolet and infrared that our eyes can't see.

Question 9

What is a shadow?

Accepted Answer

A shadow is an area where light is blocked. When something is in the way of light, it creates a dark shape behind it called a shadow.

Question 10

Why does my reflection appear in a mirror?

Accepted Answer

A mirror reflects light back to your eyes. When light hits the smooth surface of a mirror, it bounces back and shows you a reflection.

Question 11

How do sunglasses protect our eyes?

Accepted Answer

Sunglasses have special lenses that block out harmful sunlight. They help keep our eyes safe from too much light and UV rays.

Question 12

What is a prism?

Accepted Answer

A prism is a clear, glass-like object that splits white light into different colors. It shows how light can be separated just like in a rainbow.

Question 13

Why do some insects buzz towards a light bulb?

Accepted Answer

Some insects are attracted to light because they use it to navigate. At night, they might get confused and buzz around artificial lights like bulbs.

Question 14

What happens when light passes through a glass of water?

Accepted Answer

When light goes through a glass of water, it bends. This bending of light is called refraction.

Question 15

Why do some objects look shiny?

Accepted Answer

Objects look shiny when they have smooth surfaces that reflect most of the light. The reflected light makes them appear bright and shiny.

Question 16

How do plants use light?

Accepted Answer

Plants use sunlight to make food in a process called photosynthesis. They take in light, water, and air to grow and give us oxygen.

Question 17

Why is sunlight important?

Accepted Answer

Sunlight is important because it helps plants grow and gives us warmth and light. It’s also essential for keeping the Earth healthy.

Question 18

What is a laser?

Accepted Answer

A laser is a powerful beam of light that focuses in one direction. It can be used for many things, like in printers or to help doctors perform surgeries.

Question 19

Why do stars twinkle at night?

Stars twinkle because their light bends when it passes through Earth's atmosphere. The air moves around, making the light flicker.

Question 20

How do we get colors from light?

Accepted Answer

Colors come from light being split into different parts. Each color is a different wavelength of light, and when they mix, they create the colors we see.
