4) A string carries two sinusoidal waves given by fi(z,t) - A1 cos(kz - wt 37T...
4. a) The one dimensional wave equation for the variable y(z, t) can be written as: azz czacz where w is the angular frequency (rad/s), k is the wavenumber (rad/m) t is time (s). Show that y(z, t) = 12sin(wt + kz) - 24sin(wt - kz) is a valid solution. (15 marks) b) If a string is fixed at z = Om and at z = 2.4m, and its displacement when vibrating in its fundamental mode is given by: y(z,...
1.8 Two waves on a string are given by the following functions: yi(x, 4 cos(201 - 30x) (cm) y2(x, t)-4 cos(20t 30x) (cm) where x is in centimeters. The waves are said to interfere constructively when their superposition lyslyy2l is a maximum, and they interfere destructively when ly,l is a minimum. e rs yis.n and y2(x, t)? (b) At t-(n/50) s, at what location x do the two waves interfere constructively, and what is the corresponding value of lyl? (c)...
t = 0 ms (a) (4 marks) A sinusoidal wave moving along a string is shown twice in the figure at time t = 0 (top) and time t = 4t (bottom). After At = 4.0 ms, the crest travels d=6.0 cm in the positive x direction. The equation for the wave is in the form 8 mm H HHHx y(x, t) =Ym sin(kx = wt). t = 4 ms What are (i) ym, (ii)k, (iii) w, and (iv) the...
