π There are two main types of waves: mechanical waves and electromagnetic waves.
π‘ Mechanical waves propagate through a medium, while electromagnetic waves can propagate through empty space.
β‘οΈ Electromagnetic waves require the acceleration of electrons to high frequencies to propagate at the speed of light.
β‘οΈ The frequency of waves is the number of waves per second.
π The amplitude of a wave corresponds to the height of the wave.
π» The energy of an electromagnetic wave is related to its amplitude.
π Different types of electromagnetic waves are distinguished by their frequency and wavelength.
π΄π£ Visible light to the human eye ranges from red to violet.
βοΈ Infrared waves constitute thermal radiation.
π‘ Ultraviolet waves can harm the skin.
