Draw ray diagram to show the formation of images when the object in front of concave mirror is
between the centre of curvature and focus point.

Explain the sketches the formation of a virtual image in the case of a concave mirror.

Draw a ray diagram to show the image formation by a concave mirror, when the object is kept between its focus and the pole.

Explain the sketches the formation of a real enlarged image for a concave mirror

By giving sign-conventions, derive the lens formula relating object distance, image distance and focal length for a thin convex lens. Draw a ray diagram to show the formation of image of an object placed between optical centre and focus of a convex lens.

Fig.2.100 shows a convex spherical surface with centre of curature C,separating the two media of refractive indices mu_1 and mu_2 . . Draw a ray diagram showing the formation of imge of a point object O lying on the principal axis.Derive the relationship between the object and image distances in terms of the refractie indices of the wo media and the radius of curvature R of the surface.

Draw a ray diagram to show image formation when the concave mirror produces a real, inverted and magnified image of the object.

A convex lens of focal lenght 20 cm is placed coaxially wih a convex mirror of radius of curvature 20 cm.the two are kept at 15 cm apart.A point object lies 60 cm in front of the convex lens.Draw a ray diagram to show the formation of the image by the combination.Determine the nature and position of the image formed.

Form the image in case an object is moved from infinity to the concave mirror.
