Technology Review

_{By: Tania Hickey}

The basic properties (parts)

• Frequency- The higher the frequency, the closer the waves are together and the greater the energy carried by the waves.

• Amplitude-  The height of the wave from the resting position.

• Wavelength- Wavelength is a measure of the distance from the one crest to another crest.

• Crest- the Highest point of a wave

• Trough- The lowest point of a wave

• Line of origin- the original position of the wave before the wave moves through it.

The basic properties (part2)

• Transverse- Waves in which the particles vibrate is an up and down motion.

• Longitudinal wave- Waves in which the vibration of particles move back and forth.

• Mechanical wave- A wave that requires a medium to travel.

• Medium- The medium is the matter that a wave travels through.

• Reflection- Occurs when light bounces off objects.

• Diffraction- The bending of waves around a barrier or an opening

• Refraction- When light passes from one transparent material to another of a different density.

The basic properties (part3)

• Electromagnetic- Waves that transfer energy without a medium.

• Seismic Wave- A vibration that travels through Earth carrying the energy released during an earthquake.
