First, draw a rectangular slab.Mark the walls A,B,C,D.(not the vertices)Put a ball inside.Draw 2 slits S1,S2 outside the rectangle.Follow the following directions carefully henceforth:1)The diagram drawn is the top view of an arrangement.2)Medium pervading empty space is vacuum.3)Walls B,C,D are crown glass walls.4)Wall A is made of metal X5)Ball is made of metal Y6)From the slits S1,S2, light beams are incident, having very high frequency, as well as very high intensity. Frequency of incident beams is greater than threshold frequency for metal Y. Light beams are incident in such a manner that they pass through transparent walls and hit the ball. However, the never at any instant of time hit wall A.7)Initially wall A is +vely charged with(Q/4-pi-epsilon-nought)>>(l^2)where \"Q\"=charge on wall A, and , \"l\"=length of rectangle(wall A is one of the sides representing width of rectangle).8)\"d\" is the initial perpendicular distance between ball, and wall A, and (d<
