Question 1

What is light?

Accepted Answer

Light is a type of energy that lets us see things. It travels in waves and comes from sources like the sun or lamps.

Question 2

How do we see colors?

Accepted Answer

Colors appear when light hits an object and bounces into our eyes. Our eyes pick up these different wavelengths and tell our brain whether it's red, blue, or any other color.

Question 3

What is an optical illusion?

Accepted Answer

An optical illusion tricks our eyes and brain. It makes us see something that might look real, but is not exactly as it appears.

Question 4

How does a camera work?

Accepted Answer

A camera captures light to make a picture. It has a lens that focuses light onto a special part inside called a sensor or film.

Question 5

Why do mirrors reflect light?

Accepted Answer

Mirrors have a shiny surface that bounces light back. When you stand in front of a mirror, the light from your face hits the mirror and reflects back, letting you see yourself.

Question 6

What makes shadows?

Accepted Answer

Shadows form when an object blocks light. The light can't pass through the object, so it creates a dark shape behind it.

Question 7

Why is the sky blue?

Accepted Answer

The sky looks blue because light from the sun gets scattered by air. Blue light scatters more than other colors, so the sky seems blue to us.

Question 8

What is a rainbow?

Accepted Answer

A rainbow happens when sunlight hits raindrops and bends. The light splits into all its colors, making a beautiful arc in the sky.

Question 9

What does a prism do?

Accepted Answer

A prism bends light and splits it into different colors. When white light goes through a prism, it spreads out like a rainbow.

Question 10

How do eyeglasses help people see better?

Accepted Answer

Eyeglasses use lenses to focus light correctly into your eyes. If your eyes don't focus well on their own, glasses help make things clear.

Question 11

What is reflection?

Accepted Answer

Reflection happens when light bounces off a surface. Just like how a ball bounces off a wall, light bounces off things like mirrors.

Question 12

What is refraction?

Accepted Answer

Refraction is when light changes direction as it passes through something. A straw in a glass of water might look bent; that's refraction!

Question 13

Why do things look bigger under water?

Accepted Answer

Things look bigger underwater because of refraction. Water bends light, making objects underneath appear larger to our eyes.

Question 14

How does light travel?

Accepted Answer

Light travels in straight lines called rays. It moves really fast, at about 299,792 kilometers per second!

Question 15

Why do some animals see better in the dark?

Accepted Answer

Some animals have special eyes that let them see in low light. They might have bigger eyes or more light-sensitive cells than humans.

Question 16

What is a telescope?

Accepted Answer

A telescope is a tool that makes faraway things look closer. It uses lenses or mirrors to gather more light and helps us see stars and planets.

Question 17

Why do stars twinkle?

Accepted Answer

Stars twinkle because their light moves through Earth's unsteady air. The air bends the light in different ways, making the stars seem to change brightness.

Question 18

How do projectors show movies?

Accepted Answer

Projectors shine light through a film or digital image onto a big screen. They make the small picture larger so everyone can see it.

Question 19

What makes glow-in-the-dark things shine?

Accepted Answer

Glow-in-the-dark things have special materials that absorb light. They release that light slowly over time, letting them glow in the dark.

Question 20

What is a laser?

Accepted Answer

A laser is a very strong, focused beam of light. It’s so powerful that it can cut through materials or be used to make precise measurements.
