Starting with Waves Properties now...
Let's watch some video clips from youtube...
What are waves?
A wave is a disturbance that propagates through space or spacetime, transferring energy.
There are two types of waves and they are known as:
1) Transverse waves
For transverse waves the displacement of the medium is perpendicular to the direction of propagation of the wave. Examples include electromagnetic waves (radio wave, microwave, light, etc), water wave, etc.

2) Longitudinal Waves
In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. Sound is a form of longitudinal wave.

Some properties of waves include:
1) Wavelength
The distance between two consecutive points on the wave that are in phase. E.g. Distance between two consecutive wave troughs or wave crests.
Its SI units is metre (m) and the symbol is a greek letter "lamda"
2) Frequency
Wave frequency, f , is known as the number of complete wave cycles in one second. It is measured in hertz (Hz).
Wave period, T , is the reciprocal of frequency. It is measured in seconds (s).
Period = 1/frequency
3) Wave Speed
Wave Speed, v = wavelength x frequency
Wave speed, v = wavelength / Period
