A ripple tank: used to generate water waves in a sciencelaboratory

Wavelength λ
Period(t) unit: second
Amplitude a
Frequency(f) unit: hertz(Hz)
Velocity(v) formula: velocity= frequency x wavelength

A wave can be defined as the propagation ofperiodic disturbances without the transfer of anymaterial medium.
There are transverse and longitudinal waves
Transverse waves: oscillations move perpendicular to the transfer of energy
Longitudinal waves: oscillations moving parallel to the transfer of energy.

T=1/f
f=1/T
v(velocity)= fλ

used to power hydroelectric dams to bring power to many places in the world

There are two types of graphs to describe wave motion:
Displacementtime graph
Displacementposition graph

surface that joins all adjacent points which have the samephase of vibration on the wave
Phase of Vibration: when they havecompleted identical fractions of their periodic motion.
