A disturbance that transfers energy from place to place.
The material through which a wave travels.
Waves that require a medium through which to travel.
The ability to do work.
A repeated back-and-forth or up-and-down motion.
Waves that move the medium at right angles (perpendicular) to the direction in which the waves travel.
The high part of a transverse wave.
The low part of a transverse wave.
Waves that move the medium parallel to the direction in which the waves travel.
The part of a longitudinal wave where the particles of the medium are close together.
The part of a longitudinal wave where the particles of the medium are far apart.
The maximum distance the particles of a medium move away from their rest position as a wave passes through the medium.
The distance between two corresponding parts of a wave.
The number of complete waves that pass a given point in a certain amount of time.
Unit of measurement for wave frequency.
number of waves that pass a given point in one second
Period = 1/Frequency
occurs when a wave strikes an object and bounces off of it
involves a change in the direction and speed of waves as they pass from one medium to another
Diffraction of a wave
involves a change in direction of waves (bending) as they pass through an opening or around a barrier in their path
Law of Reflection
states that the angle of incidence is equal to the angle of reflection
Interference in waves
is the phenomenon that occurs when two waves meet while traveling along the same medium
Constructive (Positive) Interference
is a type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the same direction.
Destructive (Negative) Interference
is a type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction
is the distribution of electromagnetic radiation according to its energy
