Question 1

What is color in physics?

Accepted Answer

Color is the way we see light. When light hits an object, some colors bounce off and others get absorbed. We see the bouncing colors.

Question 2

How do we see colors?

Accepted Answer

Our eyes have special cells that detect light. They send messages to our brain, which tells us what color we are seeing.

Question 3

Why is the sky blue?

Accepted Answer

The sky is blue because sunlight hits air and gets scattered in all directions. Blue light scatters more, so we see a blue sky.

Question 4

What makes a rainbow?

Accepted Answer

Rainbows happen when sunlight hits raindrops in the air. The light bends and spreads out, showing us all the colors.

Question 5

Why are leaves green?

Accepted Answer

Leaves are green because they have something called chlorophyll. Chlorophyll absorbs other colors and reflects green.

Question 6

How do colors help us understand the world?

Accepted Answer

Colors help us tell things apart and notice details. They make our world interesting and help us understand what's safe or dangerous.

Question 7

Why do colors sometimes look different under different lights?

Accepted Answer

Different kinds of light have different colors. When they shine on things, they change how colors look to us.

Question 8

What is a light wave?

Accepted Answer

A light wave is a way light travels through space. It moves up and down really fast to bring light to our eyes.

Question 9

What colors make up white light?

Accepted Answer

White light is made up of all the colors mixed together. When they all combine, we see white.

Question 10

How do we see in the dark?

Accepted Answer

We can't see colors in the dark because there's no light for our eyes to detect them. We need some light to see.

Question 11

What are primary colors?

Accepted Answer

Primary colors are red, blue, and yellow. They are special because we can mix them to make all the other colors.

Question 12

Why do we have color blindness?

Accepted Answer

Color blindness happens when the special cells in our eyes can't see colors properly. It makes some people see colors differently.

Question 13

Can animals see colors?

Accepted Answer

Yes, but not all animals see colors the same way we do. Some see more colors and some see fewer.

Question 14

Why do things look black?

Accepted Answer

Things look black because they absorb all the colors of light and don't reflect any back to our eyes.

Question 15

What is a prism?

Accepted Answer

A prism is a clear, glass-like shape that bends light. When light passes through it, the prism spreads the light into a rainbow of colors.

Question 16

What does it mean when something is transparent?

Accepted Answer

Something transparent lets light pass through it. We can see through it clearly, like looking through a window.

Question 17

What does reflection do to light?

Accepted Answer

Reflection makes light bounce off surfaces. That’s how we see things like ourselves in a mirror.

Question 18

What is refraction?

Accepted Answer

Refraction is when light bends as it passes from one thing to another, like from air into water. This bending can change how we see things, like making a straw look bent in a glass.

Question 19

Why do some colors fade in sunlight?

Accepted Answer

Some colors fade because sunlight breaks down the color molecules. Over time, this makes bright colors look dull.

Question 20

Can we mix colors without paint?

Accepted Answer

Yes! You can mix colors of light. By shining different colored lights together, you can make new colors, like how stage lights work.
