Understanding Waves: Mechanical and Electromagnetic Waves Explained

An explanation of waves, including mechanical and electromagnetic waves, propagation through vacuum, and characteristics such as wavelength, frequency, and amplitude.

🌊 There are two main types of waves: mechanical waves and electromagnetic waves.

💡 Mechanical waves propagate through a medium, while electromagnetic waves can propagate through empty space.

⚡️ Electromagnetic waves require the acceleration of electrons to high frequencies to propagate at the speed of light.

⚡️ The frequency of waves is the number of waves per second.

🌊 The amplitude of a wave corresponds to the height of the wave.

📻 The energy of an electromagnetic wave is related to its amplitude.

🌐 Different types of electromagnetic waves are distinguished by their frequency and wavelength.

🔴🟣 Visible light to the human eye ranges from red to violet.

☀️ Infrared waves constitute thermal radiation.

💡 Ultraviolet waves can harm the skin.
