NAFS Review (Physics: Waves and Vibrations)

It is a disturbance that travels through a medium or space.

• Vibration

• Wave

• Trough

• Crest

The disturbance is perpendicular (at a right angle) to the direction of wave travel.

• Mechanical Wave

• Transverse Wave

• Electromagnetic Wave

• Longitudinal Wave

The distance between two successive crests or two successive troughs (or compressions or rarefactions)

• Wavelength

• Wave Speed

• Wave Distance

• Wave Energy

The waves are bouncing off a barrier or obstacle.

• Refraction

• Diffraction

• Reflection

• Transmission

It is the highest point of a wave.

• Trough

• Crest

• Amplitude

• Wavelength

It is the region of longitudinal wave where the particles of the medium are closest together.

• Rarefaction

• Combination

• Compression

• Combustion

The maximum displacement (distance) of a wave from its rest position. (height of a wave crest or depth of a trough)

• Frequency

• Wavelength

• Amplitude

• Pitch

The waves are bending as it passes from one medium to another.

• Transmission

• Reflection

• Diffraction

• Refraction

The disturbance is parallel to the direction of wave travel.

• Longitudinal Wave

• Transverse Wave

• Mechanical Wave

• Electromagnetic Wave

It is the change in frequency (in pitch) of the sound wave in relation to an observer.

• Doopler effect

• Doppler effect

• Frequency

• Vibration
