The equation of a transverse wave traveling alone a string is
y = 0.15 sin(0.79x − 13t),
in which x and y are in meters and t is in seconds. (a) What is the displacement y at x = 2.3 m, t = 0.16 s? A second wave is to be added to the first wave to produce standing waves on the siring. If the second wave is of the form y(x, t) = ym sin(kx ± ωt), what are (b) ym, (c) k, (d) ω, and (e) the correct choice of sign in front of ω for this second wave?

10. A light source emits 450 nm light that passes through a double slit, with spacing of 3 × 10−6m. Find the
angle where the third order maxima occurs.
11. The drawing shows a light ray traveling from one medium into another. If the angle of incidence is 35°,
determine the angle of refraction.
