Waves

1. Defination

1.1. a disturbance that travels through space or matter transferring energy from one place to another.

2. light

3. Sound

4. EM Spectrum

5. Properties of Waves

5.1. type of waves

5.1.1. mechanical waves

5.1.1.1. Waves that are transmitted through a medium by vibrating particles

5.1.1.1.1. example

5.1.2. Electromagnetic waves

5.1.2.1. Waves that doesn’t need a medium to move but move through the oscillation of perpendicular magnetic and electric fields

5.1.2.1.1. example

5.1.3. Transverse Waves

5.1.3.1. A wave in which the oscillation of its particles of are perpendicular with the direction of wave

5.1.3.1.1. Some are mechanical (water waves) but all EM waves are transverse waves

5.1.4. Longitudinal Waves

5.1.4.1. A wave in which the oscillation of its particles of are parallel with the direction of wave

5.1.4.1.1. All longitudinal waves are mechanical waves

5.2. Describing waves

5.2.1. Αmplitude

5.2.1.1. the maximum vertical distance from its rest position

5.2.2. Period

5.2.3. Frequency

5.2.4. Wavelength

5.2.5. wave speed
