Assertion In refraction from a plane surface, if object is virtual, then its image will be real.
Reason Plane surface always makes opposite natured image. If object is real, then image is virtual and vice-versa.

B

phase changes at constant rate at all points along the surface

C

constant phase difference continuously changes between the points

D

phase changes all over the surface

Assertion: In case of single refraction by a plane surface image and object are on same side. Reason: If object is real, image will be virtual and vice-versa.

Assertion In front of a concave mirror, a point object is placed between focus and centre of curvature. If a glass slab is placed between object and mirror, then image from mirror may become virtual. Reason Glass slab always makes a virtual image of a real object.

Assertion : Focal length of a convex mirror is 20 cm. If a real object is placed at distance 20 cm from the mirror, its virtual erect and diminished image will be formed. Reason : If a virtual object is placed at 20 cm distance, its image is formed at infintiy.

Nature of image of a real object formed by convex mirror is always

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.

State two differences between a real image and a virtual image.

A : Plane and convex mirrors can produce real images of objects. R : A plane of convex mirror can produce a real image if the object is virtual.
