sharp image of a pencil that’s 25 cm away from your eye is formed on your retina. As you move the pencil farther away from your eye, what happens to the lens of your eye in order to form a sharp image on the retina? It gets less curved, increasing its focal length It gets less curved, decreasing its focal length It does not change It gets more curved, increasing its focal length It gets more curved, decreasing its focal length
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.
