A wave travelling along the length of a string is shown in Fig. 14.4.12. Using the scale on the given axis, find
(i) The amplitude of the wave
(ii) The wavelength of the wave
(iii) If the frequency of the wave is 10 Hz, What is the speed of the wave?
(iv) What is the initial phase of the wave ?
(v) What is the phase difference between two points separated by a distance 10 cm ?
(vi) If this wave is made to travel through water what is the wavelength of the wave, if the speed of, the waves in water is 10 m/s.

Answer

(i) 0.02m (ii) 0.4m (iii) 4m/s (iv) 4m/s (iv) `pi//2` rad (v) `pi/2` rad (vi) 1m
