Solution for 115- as v=frequency X wavelength, then on substitution of the values of v and frequency we get wavelength as 1.25 m , also distance travelled is = no. Of vibration X wavelength, thus distance travelled is 81.25 m (approx 80m)Solution for 116- on comparing with equation y=a sin 2pi(kx-nt) we get the frequency as 3/2pi that is 0.477 sec-1
