Sound Waves

The phases of matter sound can travel through (check all that apply)

• solid

• liquid

• gas

• space

When waves crash together and cancel each other out, it is called.....

When waves crash together and add (constructive interference), it increases this measurement.

If these were sound waves, that increase would also increase the....

• volume

• decibels (dB)

• pitch

• frequency

This part of the ear detects different frequencies of sound waves

• ear canal

• ear drum

• semicircular canals

• cochlea

This part of the ear vibrates in response to being hit by sound waves first.

• ear canal

• ear drum

• semicircular canals

• cochlea

A disturbance that travels through a medium as a longitudinal wave

• sound
• wavelength
• pitch
• frequency

Bending of waves around an object (such as through a doorway)

• sound
• diffract
• pitch
• volume

travels through solids fastest because the molecules are closer together

• speed of sound
• wavelength
• frequency
• amplitude

The number of wavelengths that pass a point each second

• frequency
• wavelength
• pitch
• amplitude
