Question 1

What is a sound wave?

Accepted Answer

A sound wave is how sound travels through the air. It's like a ripple in water, but it moves through the air instead.

Question 2

How do sound waves make music?

Accepted Answer

Sound waves can have different patterns and speeds. When instruments create sound waves, they make patterns that we hear as music.

Question 3

Why do different instruments sound different?

Accepted Answer

Different instruments make different kinds of sound waves. This is why a piano sounds different from a guitar, even if they play the same note.

Question 4

How do our ears hear sound?

Accepted Answer

Our ears catch sound waves and send them to our brain. Our brain then understands these waves as different sounds.

Question 5

What happens to sound waves in space?

Accepted Answer

In space, there is no air for sound waves to travel through. That's why sound can't be heard in space.

Question 6

Why can you hear music through walls sometimes?

Accepted Answer

Sound waves can travel through solid objects like walls, but they change a bit when they do. That's why you might hear music from another room but not as clearly.

Question 7

What makes a sound wave loud or quiet?

Accepted Answer

The strength or size of the sound wave makes it loud or quiet. Bigger waves make louder sounds, while smaller waves make quieter sounds.

Question 8

What makes high and low pitched sounds?

Accepted Answer

High pitched sounds have fast, tiny waves, and low pitched sounds have slow, long waves. That's why a whistle sounds high and a drum sounds low.

Question 9

How does a microphone work with sound waves?

Accepted Answer

A microphone picks up sound waves and turns them into electrical signals. These signals can then be made louder or recorded as sound.

Question 10

What is an echo?

Accepted Answer

An echo happens when sound waves bounce off a surface, like a wall or a mountain, and come back to you. It’s like the sound repeating itself!

Question 11

Accepted Answer

Some sounds have patterns and rhythms that our brains find pleasant. Happy music often uses these patterns to make us feel good.

Question 12

How do sound waves travel through water?

Accepted Answer

Sound waves can move through water even better than through air. That's why whales can communicate with each other across long distances in the ocean.

Question 13

What happens to sound waves when you make music louder?

Accepted Answer

When music gets louder, the sound waves get bigger. Bigger waves can travel farther and are easier to hear.

Accepted Answer

Animals like bats and dolphins use sound waves to find things around them. They make sounds and listen for the echoes to ‘see’ with their ears.

Question 16

Why do voices sound different on recordings?

Accepted Answer

A recording changes sound waves into electrical signals and back again. This process can slightly change how our voice sounds.

Question 17

What does a sound wave look like?

Accepted Answer

Sound waves are usually invisible, but we can draw them as wavy lines that go up and down to show how they move through the air.

Question 18

Why can sound waves be dangerous?

Accepted Answer

Very loud sound waves, like explosions, can hurt our ears. They can damage our hearing if we’re not careful.
