Physics - Waves

waves

a disturbance that transfers energy

transverse waves

particles move perpendicular to direction energy is being transferred

longitudinal waves

particles move parallel to direction energy is being transferred

frequency

number of waves per second

velocity is not dependent on frequency. true or false.

true

mechanical waves

require a medium to travel through (cannot go through empty space)

electromagnetic waves

waves that can travel through empty space

list mechanical wave examples

slinky, water, earthquake S waves, string or rope

list electromagnetic wave examples

light waves & electromagnetic spectrum

list longitudinal wave examples

sound, earthquake P waves, slinky

sound travels ________ in liquids and solids than air

faster

light travels ________ in liquids and solids than empty space

slower

________ depends on sound frequency

pitch

_________ depends on sound amplitude

volume

__________ depends on light frequency

color (electromagnetic spectrum)

__________ depends on light amplitude

brightness

equation for temperature change in sound

331 + (.61 x temperature)

resonance

when the natural vibration of an object matches the frequency of a wave

constructive wave

when two waves crash on the same side add up and create a much bigger wave

destructive wave

when two waves crash on opposite sides and equal out to find a middle ground (equal waves create 0 as they pass)
