waves Crossword

The frequency (waves/sec.) of a wave can appear to change as the wave source moves toward you or away from you.
When a wave moves through a medium, the particles of the medium are moved from their rest position. This distance the particles are moved is called amplitude, the height.
The distance from the crest or trough of one wave to the crest or trough of the next wave. Measured in m or cm.
A certain number of waves pass a point in a given amount of time. Measured in waves per second.
The name given to a group of energy waves that are mostly invisible and can travel through empty space
Longest wavelength.
Absorbed by water molecules.
Felt as heat.
Can be seen as colors.
Can kill living cells.
Pass through skin, not bone.
Shortest wavelength (highest energy).
When a wave moves at an angle from a more dense medium (water) to a less dense medium (air), it is bent away from the normal.
are disturbances that transfer energy from place to place.
Any substance through which waves can travel.
The particles of the medium move up and down at right angles to the direction of the motion of the wave.
The high point of a transverse wave.
The low point of a transverse wave.
A wave in which the particles of the medium move back and forth in the direction of the wave motion.
A clap of thunder pushes the particles of air close together. The compressed particles move forward in the direction of the wave motion.
