PHS Edexcel cP4 Waves

The time taken for one wave to pass a given point.

• period

• wavelength

• frequency

• amplitude

The maximum displacement of a point on a wave from it's rest position.

• wavelength

• frequency

• amplitude

• period

The number of vibrations (or the number of waves) per second.

• period

• frequency

• amplitude

• wavelength

The distance between a point on one wave and the same point on the next wave

• period

• amplitude

• frequency

• wavelength

A wave where the particles vibrate in the same direction as the wave is travelling.

• transverse

• longitudinal

• water

• electromagnetic

A wave where the vibrations are at right angles to the direction the wave is travelling.

• longitudinal

• transverse

• sound

• seismic

Any substance through which something travels.

• medium

• large

• small

• x large

The boundary between two materials.

• interface

• medium

• border

• normal

The change in direction when waves go from one medium to another.

• reflection

• dispersion

• refraction

• diffraction

An imaginary line at right angles to a surface where a ray of light hits it.
