Sound Waves and Wave behaviors

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that is created by vibrating objects and travels through a medium (solid, liquid, or gas) as a series of compressions and rarefactions.

Why can't sound travel in space?

Back

Sound cannot travel in space because there is no matter (medium) for the sound waves to travel through.

Front

What is absorption in the context of sound waves?

Back

Absorption is the process by which sound energy is taken in by a medium, preventing it from being transmitted or reflected.

Front

What is reflection of sound waves?

Back

Reflection of sound waves occurs when sound waves bounce off a surface, such as a wall, and return to the medium from which they originated.

Front

What is refraction of sound waves?

Back

Refraction is the bending of sound waves as they pass from one medium to another, changing speed and direction.

Front

What is transmission in the context of sound waves?

Back

Transmission refers to the passage of sound waves through a medium without being absorbed or reflected.

What is frequency in relation to sound waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz), and determines the pitch of the sound.

Front

How does the medium affect the speed of sound?

Back

The speed of sound varies depending on the medium; it travels fastest in solids, slower in liquids, and slowest in gases.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the frequency increases, the wavelength decreases, and vice versa.

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay, caused by sound waves bouncing off a surface.
