Mechanical Waves
Mechanical Waves A mechanical wave is created when a source of energy causes a vibration to travel through a medium (water, air, soil, etc. )
Parts of a Wave Crest: The highest point of a wave Trough: The lowest point of a wave Wavelength: The distance between two crests
Types of waves There are three types of mechanical waves Transverse Waves Longitudinal Waves Surface Waves
Transverse Waves A transverse wave is a wave the causes the medium to vibrate at right angles to the direction that the wave travels
Longitudinal Waves A longitudinal wave is a wave in which the vibration of the medium is parallel to the direction the wave travels A longitudinal wave utilizes compression and rarefaction
Surface Waves A surface wave is a wave that travels along a surface separating two types of media Example: A wave that travels between land sea
Properties of Mechanical Waves Any motion that repeats at regular intervals is called periodic motion The time required for a complete cycle of a wave is called a period
Properties of Mechanical Waves Any periodic motion has what is called a frequency. This is the amount of cycles within a given time. Frequency is measured in Hertz (Hz)
Properties cont. The wavelength is the distance between one point on a wave to another
Properties cont. Increasing the frequency of a wave decreases its wavelength
Wave Speed To calculate the speed of waves you take the wavelength and multiply it by the frequency Wave Speed = Frequency x Wavelength
Amplitude of a wave is the maximum displacement from the resting point The more energy a wave has, the greater its amplitude
