Grade 12Wave Optics
A wave travelling on a string at a speed of 10 m/s causes each particle of the string to oscillate with a time period of 20 ms.
(a) What is the wavelength of the wave?
(b) lf the displacement of a particle is 1.5 mm at a certain instant, what will be the displacement of a
particle 10 cm away from it at the same instant?
