waves

What is the definition of a mechanical wave?

• Waves that can travel through space where there is no matter

• Waves that use a medium to transfer energy

• When two waves overlap and combine into a new wave

• The bending of waves around a barrier

What describes the amplitude of a wave?

• The number of wavelengths that pass a given point in 1 second

• Half the distance between the crest and trough

• When a wave strikes an object or surface and bounces off

• Top of one crest to the top of the next crest

Which wave causes the matter in the medium to move up and down or back and forth at right angles to the direction the wave travels?

• Electromagnetic wave

• Transverse wave

• Mechanical wave

• Compressional wave

What is the phenomenon called when a wave bends as it passes from one medium into another?

• Interference

• Diffraction

• Refraction

• Reflection

What does the Doppler effect describe?

• A change in frequency when the source of sound is moving relative to the listener

• The human perception of how much energy a sound wave carries

• The number of wavelengths that pass a given point in 1 second

• The bending of waves around a barrier

A rhythmic disturbance that carry energy without carrying matter.

Matter in the medium moves forward and backwards along the same direction the wave travels (parallel)

• longitudinal

• transverse

• electromagnetic

• doppler

An electromagnetic wave is

• waves that use a medium to transfer energy

• matter in the medium moves forward and backwards along the same direction the wave travels

• waves that can travel through space where there is no matter

• top of one crest to the top of the next crest, or from the bottom of the trough to the bottom of the next.

Wavelength is

• half the distance between the crest and trough.  From the resting to point to crest or trough.

• top of one crest to the top of the next crest, or from the bottom of the trough to the bottom of the next.

• the number of wavelengths that pass a given point in 1 second.

• from the bottom to the top of the wave.

The number of wavelengths that pass a given point in 1 second.

• frequency

• amplitude

• wave speed

• pitch
