| Q1 | (1) pi, pi/2, pi (2) (a) 5.0 m/s (b) 13 ms (c) -2.5 rad, 0.64 rad (+/- n*2pi) |
| Q2 | (1) (a) 8 m/s, -x (b) 0.32 m/s (c) 1.6 m (d) one possible value of the phase constant is 2.9 (2) c To see this, look at the wave at t=0 as shown in c. Now, what would that wave do as time goes by? What would you observe if you stared at the string particle at x=0? You should see that you get the time graph shown. |
| Q3 | (1) (b) 56 degrees measured from the vertical,
so 34 degrees from the horizontal. (2) No (Hint: How does the index of refraction change if you switch to red light?) (3) (a) 5.7 x 10^14 Hz (b) 530 nm |
| Q4 | (1) 80 mm (2) 1 m, 5 m (next are 7 m, 11 m and then you can follow the pattern) |
| Q5 | (1) 0.27 mm (the original slit was 0.50 mm) (2) 3.8 rad (this corresponds to a path length of 0.61 wavelengths in the glass) |
| Q6 | (1) 1.5 y (2) 250 ns (3) 0.96c towards the rock (4) 0.23c towards the rock |
| Q7 | (1) 40,000 m/s (2) No (3) Yes, 124 keV |
