  1. Since AC = 20 cm = 0.2 m wavelength = 2 x 0.2 m = 0.4 m Speed of wave on string = 880 x 0.4 m/s = 352 m/s Mass per unit length of string = (1.5/1000)/0.8 ...

  2. (A). Frequency of wave = 2730/(2.pi) Hz Wavelength of wave = 2.pi/172 m Hence, speed of wave = [2730/(2.pi)] x [2.pi/172] m/s = 15.87 m/s Time taken for ...

  6. 1. 172 = 2.pi/入 where 入 is the wavelength hence, 入 = 0.0365 m and 2.pi.f = 2730 where f is the frequency of the wave i.e. f = 434.5 Hz Speed of wave ...

  7. Since the wire is vibrating at fundamental note, wavelength of wave 入= 2 x length of wire. Hence, 入 = 2 x 0.4 m = 0.8 m velocity of wave v = frequency x ...
