Physical Science Chapter 9: Waves

Front

What is a transverse wave?

Back

A wave in which particles of the medium move back and forth at right angles to the direction the wave travels.

Front

What is a longitudinal wave?

Back

A wave in which particles of the medium move parallel to the direction the wave travels.

Front

What type of wave can transfer energy without matter?

Back

Radiation.

Front

What are mechanical waves?

Back

Waves that require a medium to travel through, such as sound waves.

Front

What is resonance?

Back

The process by which an object is made to vibrate by absorbing energy at its natural frequencies.

Front

What is refraction?

Back

The bending of waves as they pass from one medium to another, changing speed.

Front

What is diffraction?

Back

The bending of waves around obstacles or through openings.

Front

What is a crest in wave terminology?

Back

The highest point of a wave.

Front

What is a trough in wave terminology?

Back

The lowest point of a wave.

Front

What is the wavelength of a wave?

Back

The distance between two consecutive crests or troughs.
