Question

15 marks) ) A rectangular wave pulse is traveling to the right on a string as shown in gure If the string-2 is twice as heavy (per unit length) as string-1, and the knot joining them is massless, then calculate the length and height 151 of the reflected aud transmitted waves, and show the on the figure 5 cm Knot String-2 String-1 2 cm ) The eleetrie feld of a plane monochromatic electromagnetie wave going in free space is given by E (2г-3ý) x 10-3sinlo7(z +2y +3z-St)]. All numbers are in SI units. - Ji) What is the direction of propagation vector and polarization? fii) Show that it is a transverse wave 1+1 121 2+1+3 ii) Find B, angular frequency w, and B
