Match the following.

• wave

• wave that travels only through matter

• electromagnetic

• matter through which a mechanical wave travels

• medium

• wave formed when a charged particle like an electron vibrates

• mechanical wave

• wave in which particles of the medium vibrate at right angles to the direction that the wave travels

• transverse wave

• disturbance in matter that transfers energy from place to place
