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 (like air, water, or solids) as a series of compressions and rarefactions.

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations that are perpendicular to the direction of wave travel (e.g., light waves), while longitudinal waves have oscillations that are parallel to the direction of wave travel (e.g., sound waves).

Front

What is reflection of sound?

Back

Reflection of sound occurs when sound waves bounce off a surface, allowing us to hear echoes.

Front

What is refraction of sound?

Back

Refraction of sound is the bending of sound waves as they pass from one medium to another, caused by a change in speed.

Front

What is absorption of sound?

Back

Absorption of sound occurs when sound waves are taken in by a material, reducing the intensity of the sound.

Front

What is the relationship between frequency and pitch?

Back

Frequency is the number of waves that pass a point in one second, and it directly affects the pitch of the sound; higher frequency results in a higher pitch.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the maximum displacement of points on a wave, which is related to the loudness of the sound; greater amplitude means louder sound.

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source, commonly heard as a change in pitch.

Front

What is a medium in the context of sound waves?

Back

A medium is a substance through which sound waves travel, such as air, water, or solids.
