Basic waves and calculations

Various definitions to be learnt: 

• A = amplitude (m)- Maximum displacement from the equlibrium position 
• Wavelength - Minimum distance between 2 points on a wave oscillating in phase. 
• Frequency - Number of wavees per second 
• T (period) - Time to produce one wave 

There is an equation to help us work out 'T' , if we are given a wave and…
