how can a straight line result from two lines interfering with each other?
in destructive interference, two waves can cancel each other out of the crest of one wave lines up with the trough of the other wave
two places that you might find surface waves...
ocean or a lake
what is frequency and what unit is used when measuring frequency
frequency refers to how often an event occurs-for waves it refers to the number of cycles that pass an observer in a given amount of time. it is measured in hertz (# of cycles per second)
from which points do you measure amplitude?
from the resting point to the crest or the resting point to the trough
give an example of constructive interference from the wave lab
spring forward-when both people moved their arms the same way the wave became even bigger
give two examples of a medium that light waves might travel through
air or water
medium
a substance or material that carries a wave-consists of parts that interact with each other (think of a slinky-each part moves)
destructive interference
when multiple waves combine together to disrupt original waves-causing an even smaller wave or no wave at all (the crest of one wave lines up with the trough of another wave)
constructive interference
when multiple waves combine together to create one even bigger wave (the crests line up)
interference
when two or more waves arrive at the same place at the same time, they interact in a process called interference
rarefactions
a point where the coils are spread apart
compressions
a region where coils are pressed together
transverse waves
a wave where particle motion is PERPENDICULAR to wave motion
surface waves
waves that travel in a circular motion (these are found on the surface/top of oceans)
longitudinal wave
a wave where particle motion is PARALLEL to wave motion
what is a wave and what is transferred through a wave?
a wave is a disturbance that travels through air water or etc. energy is transferred through a wave.
