Medium - A substance through which a wave moves.

Crest - The highest point or peak of the wave.

Trough - The lowest point or the valley of a wave.

Wavelength - The distance from crest to crest or trough to trough.

Amplitude - The length of a wave from its resting position.

Frequency is the number of complete cycles per second. The time it takes for 1 cycle to occur is called period. The unit of one second is called hertz. Something that completes one full cycle is equal to 10Hz.
Natural Frequency: The frequency at which a system oscillates when disturbed.
Periodic force: A repetitive force]]> 2021-02-05 12:00:30 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167840149 Mechanical Waves 605066 https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167844004 A mechanical wave is a vibration in matter, transferring energy through a material. Not all waves are like this. For example, electromagnetic waves such as visible light are not mechanical because they can travel through the vacuum of space to reach us from the sun.]]> 2021-02-05 12:02:00 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167844004 Electromagnetic Waves 605066 https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167847935 One of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.]]> 2021-02-05 12:03:38 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167847935 605066 https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167869820 2021-02-05 12:12:30 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167869820 605066 https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167876547 2021-02-05 12:15:14 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167876547 Mediums 605066 https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167882689 2021-02-05 12:17:36 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167882689 605066 https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167893333 2021-02-05 12:21:50 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167893333 Compressions & Rarefractions 605066 https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167899701 2021-02-05 12:24:19 UTC https://padlet.com/605066/salb0xtfb9ul6peg/wish/1167899701
