gcse basics

• the wavelength is the distance of one entire oscillation of that wave
• the amplitude of a wave is the maximum displacement from the equilibrium position
• the time period is the time it takes for one entire oscillation of a wave
• formula for frequency is: $f=$$1/T$
• unit of frequency is Hertz (Hz)
• the formula for wave speed is: $v=$$fλ$
• a wave where the oscillations are perpendicular to the direction of energy transfer is a transverse wave
• a wave where the oscillations are parallel to the direction of energy transfer is a longitudinal wave
