Answer 1

Explanation:

for a) nature is real and inverted

for b) nature is virtual and errect

for finding position and size of image and object data is not sufficient

Answer 2

Answer:

the nature of image is always real and inverted and the size of image if grater than the size of object because:

m= -3 in which the sign is -ve and 3 ) 1

POSITION OF OBJ. = at focus point

TYPE OF MIRROR= Concave mirror

POSITION OF IMAGE = AT INFINITY

b)

NATURE OF IMAGE = VERTICAL AND INVERTED BECAUSE OF +VE VALUE OF M

SIZE OF IMAGE= IMAGE IS SMALLER THAN OBJECT

POSITION OF IMAGE = AT FOCUS POINT

TYPE OF MIRROR= BOTH CONCAVE AND CONVEX

POSITION OF OBJECT= AT INFINITY
