Worksheet 1 Example 3

a) Wavelength = 16cm

 Aprox. 5.5 wavelengths in 90cm 

5.5 ÷ 90 = 0.307 (Fre

0.16 (Wavelength) ÷ 0.307 (Period) =  0.52m/s

b) Only tension will affect the speed. The rest of the factors (ie. amplitude, damping)  WILL not 

affect

Set up with damping adjusted

Set up with tension adjusted

Set up with amplitude
