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.
Find the image distance and image height of the image formed on the following cases.
Then, describe whether the image formed is on the same or opposite side of the object, upright or inverted image, and smaller or bigger than the object.
1) A 21-cm high object is placed 50 cm from a concave mirror. The focal length is 27.5 cm.
2) A 26.50-cm high object is placed 30 cm from a convex mirror. The focal length is 12.50 cm.
3) An 8-cm object is placed 60 cm from a convex mirror. The focal length is 40 cm.
4) A 19-cm high object is placed 71 cm from a converging lens. The focal length is 35 cm.
5) A 26.50-cm high object is placed 40 cm from a diverging lens. The focal length is 20 c
