1. 1sin 30 = 1.45 sin Ø2 so
Ø2=20.17 Ø3 = 30 - 20.17 = 9.83 1.45 sin 9.83 = 1 sin Ø4 Ø4 = 14.33 |
2. (a) pos (b) neg (c) 1/1 + 1/q1 = 1/0.5 so q1 = 1m 2.5 - 1 = 1.5 = p2 so that 1/1.5 + 1/q2 = -1/0.5 so that q2 = -0.375 m (d) inverted (e) MTOT = (-q1/p1)(-q2/p2) = -0.25 |
3. (a) 2nd = (m + 1/2)*675 nm so d = 125 nm if m = 0. (b) 2nd = m*675 nm so d = 250 nm if m = 1. |
4. (a) ØMIN = (1.22*500 nm)/D so that D = 0.061 m (b) ØMIN = s/x so that x = 1.5x1016 m.....farther than a walk to the nearest 7-11 ! |
5. (a)Ux ' = (0.9 - 0.7)c/{1 - ( 0.9)(0.7)} = 0.54c (b) time = 300*(1 - 0.902)½/0.90c be careful....the measurement is with respect to the Earth...EVERYBODY GETS 2 POINTS MORE ON THE TEST BECAUSE OF MY INADVERTENT MISTAKE IN GRADING!!! |
