Waves

Mechanical waves

Multiple Choice

Longitudinal Compression waves move in the direction of the wave.(They are parallel to the direction of the wave)

• True

• False

Multiple Choice

A wave that has the vibration perpendicular to the direction of the wave is called:

• Longitudnal Wave

• Transverse Wave

Transverse waves

The direction of the vibration is perpendicular to the direction of the wave.

Parts of a transverse wave:

Crest: the highest point of a transverse wave.

Trough: the lowest point of a transverse wave.

Parts of a transverse wave:

Wavelength: the distant between two crests or two troughs.

Amplitude: the distance between the middle horizontal line and the highest point or between the middle line and the lowest point.

Wavelength:
