Mechanical Waves

Mechanical wave is defined as the waves produced by a disturbance in a

medium causes the vibration of particles in the medium to ________________________________

• transfer the electromagnetic

• transfer the energy.

• transfer the heat

Which part of the wave is this?

• Crest

• Trough

• Compression

• Rarefaction

Water waves and waves on a string is a type of...

• Transverse wave

• Longitudinal wave

• Both of the waves

The ____________________________ are produced by

the superposition of two progressive waves of

equal in amplitude and frequency, traveling in

opposite direction.

• stationary wave

• progressive wave

• sound wave

• heat

Sound is an example of which type of wave?

• Transverse
• Longitudinal
• Both
• Neither

What is Node?

• Zero displacement

• Back and forth displacement

• Maximum displacement

• Linear displacement

What is the wavelength?

• length between crest to crest or trough to trough

• the height of a wave

• how fast the wave goes

• the amount of times a wave passes through a certain point

Transverse wave Is defined as a wave in which the direction of vibrations of the particle is ______________________ to the direction of the wave propagation (wave speed)

What is two factors that influence sound intensity?

• node and antinode

• amplitude and distance

__________________refers to the change in

observed frequency during the relative

motion between a wave source and its

observer.
