means of transferring energy from one place to another without the transfer of matter.

The media through which waves propagate may be liquids, solids, gases, or even a vacuum in the case of

disturbance in matter that transfers energy through a medium

media of electromagnetic waves

medium of gravitational waves

The disturbance is perpendicular to the direction of propagation, usually in strings, cables and ropes.

all electromagnetic waves are

point of maximal change in the positive direction

point of maximal change in the negative direction

region where the medium is under compression, in which the particles are near each other

region where the medium is under tension, in which the particles are far from each other

one that repeats as a function of both time and position and can be described by its amplitude, frequency, wavelength, speed, and energy

The maximum displacement of a wave

time between successive cycles of a repeating sequence waves

number of cycles of a repeating sequence of events in a unit interval of time

The distance between any point on a periodic wave and the next nearest point corresponding to the same portion of the wave

Wavelength is measured between - in a wave

the product of frequency and wavelength for periodic wave

lower frequency have - wavelengths

higher frequency have - wavelengths

repetitive and fluctuates between two locations.

repeats a cycle of motion with a characteristic time

the time to complete one cycle of periodic motion

mechanical, longitudinal wave

is the apparent change in the frequency of a wave caused by relative motion between the source of the wave and the observer.
