Different types of waves and characteristics
Electromagnetic waves
EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field
Electromagnetic spectrum
Gamma rays
X-rays
Ultraviolet
Infared radiation
microwaves
radio
Transverse waves
transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
ex.seismic S (secondary) waves, and electromagnetic
Longitudinal waves
wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
Examples:
sound waves.
ultrasound waves.
seismic P-waves.
Waves in general
Periods
The wave period is the time it takes to complete one cycle.
Frequency
Frequency is the number of waves that pass a fixed point in a given amount of time.
Properties of waves
refraction
Refraction of waves involves a change in the direction of waves as they pass from one medium to another.
diffraction
the spreading of waves around obstacles. The phenomenon is the result of interference
reflaction
Reflection involves a change in direction of waves when they bounce off a barrier
