- I can tell you all about mechanical and electromagnetic waves

- First, both Mechanical and EM waves can be transverse but only mechanical waves can be both transverse and longitudinal.
- Electromagnetic waves also include an electromagnetic spectrum where frequency and energy of waves increase as it goes to the right

- From low to high frequency and energy, the electromagnetic spectrum include radio waves, microwaves, infrared , visible light, ultraviolet, x-ray, and gamma rays.
- Red has the lowest frequency and energy while violet has the highest frequency and energy
- The visible light spectrum can be remembered as ROYGBIV (red, orange, yellow, green blue, indigo, violet) The frequency and energy of these colors also increase as you go to the right
- Also, wavelength and frequency are inversely proportional, frequency and energy are proportional and amplitude and energy are also proportional. Inversely proportional means that as wavelength increases, frequency decreases. Proportional means that as frequency or amplitude increase, energy also increases.
- In a transverse wave, the highest point is called the crest and the lowest is a trough. The wave length is the distance between two crests and the amplitude is the distance of the crest from the resting point

- In a longitudinal wave, energy travels in a series of compress ions and rare factions. Compressions are the densest part of the wave while rare factions are the least dense.
