question statement:

Two sinusoidal waves of the same frequency travel in the same direction along a stretched string. Their amplitudes are 3.0 mm and 6.0 mm respectively; they produce a resultant wave with an amplitude of 7.0 mm. The phase constant of the 3.0 mm-wave is 0. What is the phase constant of the 6 .0 mm wave? (b) A string oscillate according to the equation What are the amplitudes of the individual waves?

Q.2. (a) Two sinusoidal waves of the same frequency travel in the same direction along a stretched string. Their amplitudes are 3.0 mm and 6.0 mm respectively, they produce a resultant wave with amplitude of 7.0 mm. The phase constant of the 3.0 mm wave is 0. What is the phase constant of the 6 0 mm wave? (b) A string oscillate according to the cquation y' = (0.005m)sin [IG x 10*m)x] cos( (40ns"*)e) What are the amplitudes of the individual waves?
