WAVES

WAVES

1. Waves involve the transport of energy without the transport of matter. can be described as a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter.

2. MECHANICAL WAVES

   • A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. the wave travels is called the medium plural, media
     • TRANSVERSE WAVES
       • transverse wave is a moving wave whose oscillations are perpendicular to the direction of the wave or path of propagation.
         • Example: waves that can be created on a horizontal length of string by anchoring one end and moving the other end up and down.
           • Parts: The crest is the top of the wave. The trough is at the bottom of the wave. The wavelength is the length of the wave. The amplitude of a wave is the highest amount of vibration that the medium gives from the rest position.
     • COMPRESSIONAL WAVE
       • (such as a sound wave) propagated by the elastic compression of the medium, they are also called longitudinal wave
         • ripples on the surface of water. vibrations in a guitar string. a Mexican wave in a sports stadium.
           • Parts: Picture of a Wave. Crest and Trough. Amplitude. Wavelength. Frequency.

3. ELECTROMAGNETIC WAVES

   • Electromagnetic waves are also called EM waves, they are waves that are created as a result of vibrations between an electric field and a magnetic field
     • Example: include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Radio waves have the lowest energy and frequency and the longest wavelength.
       • Parts: Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation.
