Simulator . Newton's rings are a fun demonstration of the wave nature of light, and also of the fact that white light is made up of many components of different wavelengths. ... Ans : Because the plano convex lens and the plane lens both are in contact and at that particular place the centre dark ring will appear. The ray treatment of light is called geometrical optics as distinct from physical optics, which attempts to explain the objective phenomena of light. 13 0 obj Note the reading on the vernier scale of the microscope.
