Transcript of Waves and its properties
Frequency:f = velocity ÷ wave lengthf = 5 m/s ÷1 m f= 5 cycles/sec
Time period:T=1/fT = 1/5 cycles/sT = .2 sec
When a wave encounters a surface, four interactions can occur:
Reflection, Refraction, Diffraction, or Absorption.
• What happens when one pulse is on top of the string and the other is on the bottom?
• When the pulses meet in the middle, they cancel each other out.
• During destructive interference, waves add up to make a wave with smaller or zero amplitude.
