Problem 1: Spherical mirrorConsider a spherical mirror of radius 2 m, and rays which go parallel to the optic axis. What is theposition of the point where the reflected rays intersect the optic axis?(i) 0.25 m from the mirror.(ii) 0.5 m from the mirror.(iii) 1 m from the mirror(iv) 2 m from the mirror.(v) Infinity, ie. the rays never intersect the optic axis. Problem 2: LensThe lens in the picture (one of the surfaces is flat, light entering from the left) is characterized by tworadiuses of curvature, R1andR2. Which statement about the values ofR1andR2is correct?(i)R1=[infinity],R2<0.(i i)R1=[infinity],R2>0.(iii)R1> 0,R2=[infinity].(iv)R1<0,R2=[inf inity].(v)R1> R2>0.Physics 9B LectureAn alternative derivation is to start with a very wide lens with the two surfaces separated by L, calculate (using the image for the first surface as the object for the second) where an incoming ray parallel to the optic axis eventually crosses the optic axis (a

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
