Terms in this set (21)
A repeating disturbance that transfers energy as it travels through matter or space.
Matter through which a wave travels.
A wave that can only travel through matter.
A wave in which the matter in the medium moves at right angles to the direction of the wave, has crests and troughs.
A wave in which the matter in the medium moves back and forth along the direction that the wave travels.
The highest point on a transverse wave.
The lowest point on a transverse wave.
The denser region of a longitudinal wave.
The less dense region of a longitudinal wave.
The distance between one point on a wave and the nearest point just like it.
The number of wavelengths that pass a fixed point each second; expressed in hertz (Hz).
The amount of time it takes one wavelength to pass a fixed point; expressed in seconds.
Wave Speed Equation
Wave speed (in m/s) equals frequency (in Hz) times wavelength (in m). v = f λ
A measure of the size of the disturbance of a wave, related to the energy that it carries.
Law of Reflection
The angle of incidence is always equal to the angle of reflection.
The bending of a wave caused by a change in its speed as it travels from one medium to another.
The bending of waves around an obstacle; can also occur when waves pass though a narrow opening.
The process of two or more waves overlapping and combining to form a new wave.
A wave pattern that forms when waves of equal wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other; does not appear to be traveling.
A point in a standing wave at which the interfering waves always cancel.
The process by which an object is made to vibrate by absorbing energy at its natural frequencies.
