Question 1

What is light?

Accepted Answer

Light is a type of energy that we can see. It travels from the Sun to Earth, helping us see everything around us.

Question 2

Why is the sky blue?

Accepted Answer

The sky is blue because sunlight scatters in the air, spreading out in different directions. Blue light scatters more than other colors, making the sky look blue.

Question 3

What are colors?

Accepted Answer

Colors are different kinds of light that our eyes see. Each color is a part of sunlight, and when all the colors mix together, they look white.

Question 4

How does a rainbow form?

Accepted Answer

A rainbow forms when sunlight passes through raindrops. Each drop acts like a tiny prism, bending the light and separating it into different colors.

Question 5

What is reflection?

Accepted Answer

Reflection is when light bounces off a surface, like a mirror. This is how we can see ourselves in shiny things.

Question 6

What is refraction?

Accepted Answer

Refraction is when light bends as it passes through something, like water or glass. This bending can make objects look different or change their colors.

Question 7

Why do objects have different colors?

Accepted Answer

Objects have different colors because they reflect certain colors of light and absorb others. A red apple looks red because it reflects red light.

Question 8

How do our eyes see colors?

Accepted Answer

Our eyes see colors using special cells that sense red, blue, and green light. These cells send signals to our brain, which mixes them to make all the colors we see.

Question 9

What makes a mirror shiny?

Accepted Answer

A mirror is shiny because it has a smooth, reflective surface. This surface bounces light back at us, showing a clear picture of whatever is in front of it.

Question 10

Why does water look blue in the ocean?

Accepted Answer

Water looks blue in the ocean because it absorbs colors like red and reflects blue light more. The deeper the water, the bluer it looks.

Question 11

What is a prism?

Accepted Answer

A prism is a special piece of glass or plastic that can split light into a rainbow of colors. It bends the light, showing how light is made up of different colors.

Question 12

How can we make shadows?

Accepted Answer

Shadows are made when an object blocks light from getting to a surface. The blocked area stays dark, creating a shadow shape.

Question 13

Why do objects look different underwater?

Accepted Answer

Objects look different underwater because light bends when it goes from air to water. This bending can make things appear larger or closer than they really are.

Question 14

What happens to light when it hits a rough surface?

Accepted Answer

When light hits a rough surface, it scatters in different directions. This scattering makes the surface look dull instead of shiny.

Question 15

Why do straws look bent in a glass of water?

Accepted Answer

Straws look bent in a glass of water because of refraction. The light bends when it moves from the water to the air, making the straw look like it's broken.

Question 16

What are primary colors of light?

Accepted Answer

Primary colors of light are red, green, and blue. These colors can mix in different ways to make all the other colors we see on screens and in lights.

Question 17

Why do we use lights at night?

Accepted Answer

We use lights at night because there's not enough sunlight. Lights help us see things clearly and safely when it's dark.

Question 18

How does light help plants grow?

Accepted Answer

Light helps plants grow by giving them energy. Plants use sunlight to make their food in a process called photosynthesis.

Question 19

What is the speed of light?

Accepted Answer

Light travels incredibly fast, faster than anything else. It moves at about 300,000 kilometers per second, so it can circle the Earth in just a blink of an eye.

Question 20

Why do we see lightning before we hear thunder?

Accepted Answer

We see lightning before we hear thunder because light travels faster than sound. Even though lightning and thunder happen at the same time, the light reaches us first.
