Conclusion Of Waves

Some apparatus used to study waves:

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

Terms used:

Wavelength λ

Period(t) unit: second

Amplitude a

Frequency(f) unit: hertz(Hz)

Velocity(v) formula: velocity= frequency x wavelength

What are Waves?

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.

Formulas

T=1/f

f=1/T

v(velocity)= fλ

Waves can be useful to humans:

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

Graphs

There are two types of graphs to describe wave motion:

Displacementtime graph

Displacementposition graph

Wavefront

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.

Some waves can be harmful to people

such as ultraviolet waveswhich can cause skin cancer
