Sound Waves Through a Medium

A longitudinal wave is described as-

• a wave that flows in exactly a straight line.

• a wave that transverses through the core of the Earth.

• a wave vibrating at right angles to the direction of its propagation—like wiggles.

• a wave (such as a sound wave) in which the particles of the medium vibrate in the direction of the line of advance of the wave

A transverse wave is described as-

• a wave that transverses through the core of the Earth.

• a wave (such as a sound wave) in which the particles of the medium vibrate in the direction of the line of advance of the wave

• a wave vibrating at right angles to the direction of its propagation—like wiggles.

• a wave that flows in exactly a straight line

Wavelength is-

• waves passing a given point per second. Oscillations of a wave per second. (Measured in Hertz.)

• the speed at which a wave pulse travels.

• the time it takes one wavelength to pass a fixed point.

• the length of one wave cycle.

Velocity of a wave is-

• waves passing a given point per second. Oscillations of a wave per second. (Measured in Hertz.)

• the length of one wave cycle.

• the speed at which a wave pulse travels.

• the time it takes one wavelength to pass a fixed point.

A “period” when referring to waves is-

• the length of one wave cycle.

• the time it takes one wavelength to pass a fixed point.

• waves passing a given point per second. Oscillations of a wave per second. (Measured in Hertz.)

• the speed at which a wave pulse travels.

Frequency is-

• waves passing a given point per second. Oscillations of a wave per second. (Measured in Hertz.)

• the length of one wave cycle.

• the speed at which a wave pulse travels.

• the time it takes one wavelength to pass a fixed point.

Refraction occurs when-

• a wave bends around a barrier.

• a wave bends as it moves from one medium to another.

• the substance through which a wave can travel is moving rapidly up and down.

• when a wave strikes an object or surface and bounces off.

A sound wave is also considered a _______________________ because matter in the medium moves forward and backward along the same direction that the wave travels.

• Compression wave

• Surface wave

• Large wave

• Transverse wave
