Sound Waves

Front

What does the speed of a sound wave depend on?

Back

The speed of a sound wave depends on both air temperature and the medium through which it travels.

Front

What is echolocation?

Back

Echolocation is a method used by bats to locate objects, such as mosquitoes, in the air by emitting sound waves and interpreting the echoes that return.

Front

What is diffraction in the context of sound waves?

Back

Diffraction is the bending of sound waves around an object, such as through a doorway.

Front

Why do sound waves travel fastest through solids?

Back

Sound waves travel fastest through solids because the molecules in solids are closer together, allowing for quicker transmission of sound.

Front

Why is carpet used in school libraries?

Back

Carpet is used in school libraries to help absorb sounds and keep the environment quiet.

Front

What is the definition of sound waves?

Back

Sound waves are vibrations that travel through a medium (solid, liquid, or gas) and can be heard when they reach a person's or animal's ear.

Front

What is the relationship between frequency and pitch?

Back

Frequency refers to the number of waves that pass a point in a given time, and pitch is how high or low a sound is perceived, which is directly related to frequency.

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the sound wave, which determines the loudness of the sound; higher amplitude means louder sound.

Front

What is wavelength in sound waves?

Back

Wavelength is the distance between two consecutive peaks or troughs in a sound wave, affecting the sound's pitch.

Front

How does temperature affect the speed of sound?

Back

As temperature increases, the speed of sound also increases because warmer air has more energy, allowing sound waves to travel faster.
