A ray is incident at a height h 1 cm on an infinite stack of very thin convex lenses each having thickness 1 cm and focal length 100 cm as shown in figure As a result of this the ray follows a curved path Then which of the options is are correct Assuming ray to be paraxial always h for Rough work focco A The ray will again be parallel to x axis after travelling a distance of 10 1 10 B Whenever it cuts the x axis it makes an angle of magnitude tan C The deviation in the ray after crossing the very first lens is nearly 0 01 m D Whenever it cuts the x axis it makes an angle of magnitude tan 1 metres is x directin with x axis with x axis
