Two converging lenses, one of focal length of 30 cm and the second one of focal length 10 cm are placed 100 cm apart. If an object 2 cm height is placed to the LEFT of the first lens at 60 cm, answer the following • What is the position of the image due to the first lens? • What is the new object distance with respect to the second lens? • What is the position of the final image due to the system of lenses? • What is the magnification and size of the final image?
Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
