ELECTROMACNETIsm
1.- Mechanical Waves
Types of waves
What are waves?
-Mechanical Waves-Electromanegtic Waves
Rhythmic disturbances that carry energy without carrying matter
Waves that need matter (medium) to transfer energy:
Electromagnetic waves travel VERY FAST – around 300,000 kilometres per second (the speed of light).
2.-Electromagnetic Waves
Waves that DO NOT NEED matter (medium) to transfer energy
ELECTROMAGNETISM
Electromagnetcic Spectrum
Uses
Low and very-low frequencies (below 50 kHz) are used in some underwater communications (hydrophone), or even metal detectors, and are emitted by transmission lines for electricity
+The different frequency bands each have their applications, including the following:
The electromagnetic spectrum illustrates the range of wavelengths and frequencies of electromagnetic waves.

X-rays are used for medical radioscopy, but also for the security of public places (luggage scanners) as well as in industry, especially for the checking of metallurgy parts like jet turbine blades.
