Properties of Waves

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum distance that a point on a wave moves from its rest position. In sound waves, larger amplitude means louder sound.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the particles of the medium move parallel to the direction of the wave's travel, such as sound waves.

Front

What is the relationship between frequency and pitch in sound?

Back

Higher frequency waves produce higher pitch sounds, while lower frequency waves produce lower pitch sounds.

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is reflection in terms of waves?

Back

Reflection is when a wave bounces back after hitting a barrier, such as light reflecting off a mirror.

Front

What is refraction?

Back

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

Front

What is the difference between sound waves and light waves?

Back

Sound waves are mechanical waves that require a medium to travel through, while light waves are electromagnetic waves that can travel through a vacuum.

Front

What is the role of a medium in wave propagation?

Back

A medium is the substance through which a wave travels, such as air, water, or solid materials.

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.
