An object is placed at a distance equal to 2f in front of a convex lens. Draw a labelled ray diagram to show the formation of image. State two characteristics of the image formed.
When an object is placed between F and 2F in front of a convex lens, the image formed is
When an object is placed between O and F_(1) in front of a convex lens, the image formed
a) An object is placed well outside the principle focus of a convex lens. Draw a ray diagram to show how the image is formed, and say whether the image is real or virtual. b) What is the effect on the size and position of the image of moving the object i) towards the lens, and ii) away from the lens?
An object is placed in front of a mirror. Arrange the following steps in sequential order to determine the nature of the mirror. (A) Check whether the image formed is virtual or real. (B) Check whether the virtual image formed is dimished, magnified or same size as that of the object. (C) If the image formed is real, the mirror used is concave. (D) If a magnified vritual image is formed, the mirror is concave, if a dimished virtual image is formed, the morror is convex and if size of the image is equal to the size of the object, plane mirror is used.
For each position of the object given below, draw a ray diagram showing the formation of image in a convex lens when the object is
