Physics
Frequency f = number of oscillations/times taken = 50/30s = 1.66Hz Velocity of wave v = distance/time = 0.5m/15s = 0.033m/s v = fλ λ = v/f = 0.033/1.66 = 0.02

Physics
A. Focal length = half of radius of curvature = > f = 25/2=12.5 cm B. 1/di + 1/do = 1/f 1/di + 1/-40 = 1/-12.5 di = 18.18m C. M = -di/do = 18.18/-40 = -.45 Since the magnitude of image M is less than 1, the image is diminished. D. M = hi/ho hi = M*ho = -.45 * 10= -4.5 E. Th...
