Lesson 5.2 Homework: 1. A stone dropped vertically in a pool of water makes the water particles vibrate up and down with a frequency of 2 Hz. The distance between two consecutive crests is o.8 m, (i) What is the wavelength of the wave? (ii) What is the period of the wave? (iii) What is the velocity of the wave? (iv) How many waves are there in a distance of 2.4 m? (v) What is the phase difference between particles that are separated by a distance of (a) 0.8 m, (b) 1.6 m, (c) 0.4 m, (d) 0.2 m (vi) Is the wave longitudinal or transverse? Why? 2. One end of a 5-m long string is tied to a pole and the free end is moved up and down 5 times in 2 seconds. A pulse reaches the pole in 2.5 s. (i) What is the frequency and period of the wave on the string? (ii) What is the speed of the wave on the string? (iii) What is the wavelength of the wave on the string? (iv) How many waves are on the string? (v)
