Understanding the wave
• Waves are vibrations that propagate through
  the medium.
• Waves carry energy from one place to
  another.
• Periodic wave is a wave motion on a regular
  basis and repeatedly having a continuous
  source of disturbance and oscillates, in the
  form of vibration or oscillation.
Terminology of a Wave
• Highest points on the wave called the crest of
  a wave, while the lowest points called the
  trough of the wave.
• Amplitude (A) is the maximum
  displacement, is a maximum height of the
  peak, or maximum depth of the
  trough, relative to its equilibrium position.
Terminology of a Wave
• Wavelength (λ) is distance of two consecutive
  points in the same position.
• Frequency (f), is the number of peaks or a
  complete cycle that passes through a point
  per unit time.
• Period (T), is the time required for one
  oscillation, is the time elapsed between two
  consecutive peaks that pass through the same
  point in space.
Terminology of a Wave
• Wave velocity (v) is the distance traveled in unit time
   wave.
• If a wave to travel one wavelength (λ), in one period
  (T), then the wave velocity is equal to λ / T, or v = λ/T.
  Because 1/T = f then :


      The Wave Equation                 v=ƒ
Terminology of a Wave
TYPES OF WAVES
Waves are classified into different types according
to their natures :

                        WAVES

        Mechanical waves            Electromagnetic waves


Transverse waves   Longitudinal waves   Transverse waves
1. Mechanical Waves
• Mechanical waves in a wave that requires
  propagation intermediary medium.
  Mechanical waves cannot travel through
  vacuum.
• Mechanical vibration waves originating from a
  point or a particle in space.
• Examples : Water waves, sound
  wave, vibration of spring, etc.
2. Electromagnetic waves
electromagnetic waves in a wave that not
requires propagation intermediary medium.
Electromagnetic waves from vibration load - the
electrical charge in the atom or particle.
Examples of light waves, X-rays, radio
waves, micro-waves.
1.1 Transverse waves
Transverse wave is a wave vibration direction
perpendicular to the direction propagation. A
transverse wave consists of one peak and one
trough.
For example : water surface waves, rope waves.
1.2 Longitudinal waves
Longitudinal wave is a wave vibration direction parallel to
the direction propagation. A longitudinal wave consists
of a single dense and strain.
For example : sound wave and waves on the spring.
Common Characteristics of Waves
1. Reflection
   Reflection is the event of return of all or part
   of a particle or a wave file when the file was
   to meet with the boundary between the two
   mediums.
Common Characteristics of Waves
2. Refraction
   Refraction is changes the direction of the wave
   when the waves enter into a new medium that
   resulted in a wave moving at a different pace.




   This effect is a consequence of the wave
   equation, v = ƒ . Since ƒ is constant, a decrease in
   v produces a decrease in .
Common Characteristics of Waves
3. Diffraction
   Diffraction is the spreading or bending of a wave
   incident at the time of the wave is passing through
   openings or around the tip of the barrier.




   The wavelength of the wave is not changed in
   diffraction
Common Characteristics of Waves
4. Interference
   The interaction between two or more wave motion
   that affects a part of the same medium so that the
   momentary interruption in the alloy is the sum of the
   wave vector of disturbances at each moment is an
   explanation of the phenomenon of wave
   interference.
Common Characteristics of Waves
5. Dispersion
  Dispersion is the incident light beam that the
  decomposition of a mixture of several
  wavelengths into its components due to
  refraction.
Common Characteristics of Waves
6. Polarization
   Polarization is a process of restriction vector
   vibrations that form a transverse wave so that it
   becomes one-way.
