Transverse waves - motion of the wave is at right angles to the direction of the vibration of the wave. These are like water waves, they travel as a series of peaks and troughs., Longitudinal waves - motion of the wave is the same direction as the direction of vibration of the wave. These are like sound waves, they travel as a series of compressions and rarefactions., Amplitude of a wave - is a measure of the energy carried by the wave. It is measured from the normal position to the top of a crest or the bottom of a tough., Wavelength - is the distance that the wave takes to repeat itself. Normally measured from one crest of the wave to then next. It is measured in meters, Frequency of a wave - is the number of waves that pass a point in one second. It is measured in hertz, where 1 Hz = one wave per second., Wave speed - is the distance that a wave travels in 1 second. It is measured in metres per second, m/s, High frequency waves - have a shorter wavelength, Low frequency waves - have a longer wavelength, Wave speed = - distance ➗ time OR frequency ❌ wavelength, All electromagnetic waves - travel at the speed of light 300 000 000 m/s or 3 x 108 m/s, Water waves - like surf, travel at around 4 m/s, Radio waves - Longest wavelength and lowest frequency. Used in communication, e.g., broadcasting, Wi-Fi, and Bluetooth., Microwaves - ovens and communication (satellite communication), Infrared waves - Detected as heat. Used in night vision equipment, remote controls, and some types of heating., Visible light - The range of wavelengths that can be detected by the human eye. Different colors have different wavelengths, Ultraviolet - Not visible, but can cause sunburn. Used in fluorescent lamps and in security marking (e.g, on banknotes)., X rays - Used in medical imaging (X-ray radiography) to see inside the body., Gamma rays - Shortest wavelength and highest frequency. Used in the treatment of cancer and in detecting flaws in metal castings.,
