Materia
1. Pages waves (Wave Front) waves are two types of wave front curvature. Caused by stem
The wave is a ( small) and Wavefront straight line. The origin of the wave that is straight .
2. Reflection (Reflection) waves on the surface of the object wave barrier falls .The angle of incidence is equal to the reflection angle .
3. Refraction (Refraction) on the wave.Moving through a medium ( water) with different depth Consequently , the resulting wave refraction if the wave.Moving from deep water to shallow water waves over Ben.Approached the normal To see waves in deep water.A range wider than the distance between the waves .The waves in shallow water to shallow water.
Deep wave is deflected out of the normal line to see .2Waves in shallow water , with a range narrower than the distance between the front of the wave , the wave speed in deep water .
Deep water than in shallow water speed . Due to the frequency of the wave is constant.
4. Diffraction (Diffraction) when waves move through the block or narrow (Slit).
Waves passing through the diffraction barrier or distributed objects home. If the channel has a width less.Wavelength of the wave is made clearly visible diffraction . Due to the diffractionmore
5. Wave standing (Standing Wave) or a static (Stationary Wave) is a wave caused by wave 2.
Waves with the same frequency Mobile park Or caused waves when hitting the object and reflection.Back in the opposite direction Then moving garden with incident wave . Both were born to make waves .Amplitude Interference with the highest and lowest Antinode called Node alternately arranged so forth .And visible on the surface of a wave at the time, so -called " standing wave " or "wave static " .
6. Interference (Interference) when the waves from two or more waves meet at a location moves ., Or the resulting waves are added together . (Constructive Interference) , with the Maximum Amplitude .Or cancel (Destructive Interference Amplitude with minimum or zero.
7. Principle of Huygens 's (Huygen's Principle) states that " every point on the wavefront .
Wave generator and frequency and wavelength of a wave is the same " .
Methods used to conduct experiments
