the material through which a substance changes from solid to liquid

the highest point of a transverse wave

the lowest point of a transverse wave

a wave that causes a medium to vibrate at right angles to the direction in which the wave travels

an area of a longitudinal wave where the particles of the medium are close together

an area of a longitudinal wave where the particles of the medium are spread out

the bending of a wave as it enters a new medium at an angle

the bending of a wave as it moves around an obstacle or passes through a narrow opening

the interaction of two or more waves that combine in a region of overlap

the interaction among two or more waves in which displacements combine to produce a wave with larger displacement

a wave that appears to stay in one place and does not seem to move through a medium

a point on a standing wave that has no displacement from the rest position

a point of maximum displacement midways between two nodes in a standing wave

a longitudinal wave consisting of compressions and rarefactions which travel through a medium

a unit that compares the intensities of different sounds

a physical response to the intensity of sound modified by physical factors
