A real image is always erect.

A virtual image is always .................. (inverted/erect) and is formed behind the mirror.

Virtual image are always inverted

If the image formed by a mirror for all positions of the object in front of it is always erect diminished, what type of mirror is it? Draw a ray diagram to justify your answer . Where and why do we generally use this type of mirror?

Assetion : Rear view mirror of vehicles is a convex mirror. Reason : It never makes real image of real objects.

If the image formed by a lens for all positions of an object placed in front of it is always erect and diminished, what is the nature of this lens ? Draw a ray diagram to justify your answer. If the numerical value of power of this lens is 10 D, what is its focal length in cartesian system ?

Assertion : If magnification of real object is -2. Then, it is definitely a concave mirror. Reason : Only concave mirror can make real images of real objects.

The image formed in a convex mirror is always erect and enlarged.

A convex mirror is used to form an image of a real object. The image (i) always lies between the pole and the focus (ii) is dimished in size (iii) is erect (iv) is real

If the image formed by a spherical mirror for all positions of the object placed in front of its is always erect and diminished , what type of mirror isit ? Draw a labelled ray diagram to support your answer.

A real image is formed by a convex lens. If we put a concave lens in contact with it, the combination again forms a real image. The new image
