I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
what will happen if gravity becomes zero?is it possible in earth?
(a) You have studied that plane and convex mirrors produce virtual images of objects. Can they generate real image under some circumstances? Explain. (b) A virtual image we a
