A single disturbance that travels through a medium.

A wave where the particles of the medium move perpendicular to the direction of the wave's travel.

The maximum displacement of a particle from its rest position.

When two or more waves overlap, their amplitudes add up.

When two wave crests overlap, their amplitudes add up to create a larger wave.

When a wave crest overlaps with a trough, their amplitudes cancel each other out, resulting in a smaller wave.

The number of complete wave cycles that pass a point per second.

The time it takes for one complete wave cycle to pass a point.

The highest point on a wave.

The lowest point on a wave.

The distance a point on a wave travels per unit time.

A wave where the particles of the medium move parallel to the direction of the wave's travel.

A wave that travels through a vacuum.

The distance between two successive points in phase on a wave.

The ability of a wave to bend around obstacles.

The bouncing of a wave off a surface.

The bending of a wave as it passes from one medium to another.

The merging of two or more waves.

The sensation of sound.

The sensation of highness or lowness of sound.

A sound wave that is too high in frequency to be heard by humans.

A sound wave that bounces back from a surface.

The speed at which sound travels through a medium.

A negatively charged particle found outside the nucleus of an atom.

The smallest unit of electric charge.

A neutral particle found in the nucleus of an atom.

A positively charged particle found in the nucleus of an atom.

The separation of positive and negative charges within a material.

The idea that electric charge exists in discrete units.

The principle that states that charge cannot be created or destroyed, only transferred.

The principle that states that the total charge of an object is always a whole number multiple of the elementary charge.

The process of becoming electrically charged by rubbing two different materials together.
