PRESENTATION OUTLINE
Waves transfer energy from one point to another without transferring matter. They consist of disturbances which transfer the energy in the direction the wave travels without transferring matter.
There are two types of waves:
Transverse waves
Longitudinal waves
Transversal waves cause the particles of the medium to vibrate perpendicular to the direction of the wave.
Which means it's created by a disturbance perpendicular to the wave.
They are used in microwaves, radios, and x-rays.
Longitudinal waves cause the particles to move parallel to the direction of the waves.
Longitudinal waves create sound and that is used for music and tv's
A wave whose equiphase surfaces form a family of concentric spheres; the direction of travel is always perpendicular to the surfaces of the spheres.
Wave length- 2.5
Wave frequency- 5.2Hertz
Wave speed- 13 cm per second
A plane wave is a constant-frequency waves that are infinite parallel planes of constant amplitude .
Wave length- 2.5
Wave frequency- 5.2 Hertz
Wave speed- 13 cm per second
Two point source interference
A two-point source interference pattern always has an alternating pattern of nodal and antinodal lines.
When a ray of light, or radar pulse,is reflected from a smooth surface the angle of reflection is equal to the angle of incidence.
Diffraction involves a change in direction of waves as they pass through an opening or around a barrier in their path.
