1. Mechanical Waves
2. What is a mechanical wave? A disturbance in matter that carries energy from one place to another. Require a material to pass through called a medium. A medium can be a solid, liquid, or a gas. 3 types of mechanical waves. 1. Transverse waves 2. Longitudinal waves 3. Surface waves
3. Transverse waves Cause the medium to vibrate at right angles to the direction of wave motion. Wave motion Slinky motion
4. Parts of a transverse wave Rest position wavelength wavelength node
5. Crest the top of a wave. Trough the bottom of a wave. Wavelength the distance from crest to crest or trough to trough. Node where the wave intersects the rest position. Amplitude distance from the rest position to a crest or trough measures energy. Frequency how many times the wave cycles in a given time period. Usually measured in Hertz (Hz) cycles per second Low frequency High frequency
6. Wavelength and Frequency These 2 are related As one increases, the other decreases. Low frequency, large wavelength High frequency, small wavelength
7. Longitudinal Waves Compression waves Move the medium the same direction as the wave. Made from compressions and rarefactions Wave motion Slinky motion
8. Surface Waves Travel along the surface separating 2 media. Ocean waves travel between water and air Have characteristics of both longitudinal and transverse waves. Transverse part causes up and down motion. Longitudinal part causes back and forth motion.
9. Wave Speed Speed = frequency X wavelength f speed (m/s) f = frequency (Hz) wavelength (m)
