Images formed by concave mirror using ray diagram

Question 1 The image formed by concave mirror is seen to be virtual,erect and larger than the object.What is the position of the object?

Question 2 The image formed by concave mirror is seen to be real,inverted and of same size.What is the position of the object?

Question 3 Where should an object be placed in front of a concave mirror so as to obtain highly enlarged image?

Question 4 Write the applications of concave mirror?

Question 5 Where should an object be placed in front of a concave mirror so as to obtain image between F and C?

Question 6 Where should an object be placed in front of a concave mirror so as to obtain image beyond C?

Images formed by concave mirror using ray diagram

1)object is at infinity

a)Image is formed at focus.

b)It is real and inverted.

c)It is highly diminished.

 2)Object is beyond C
Object is beyond C

a)Image is formed between F and C.

b)Size of image is less than that of object.

c)It is real and inverted.


3)Object is at centre of curvature

Object is at centre of curvature
a)Image is formed at C.

b)It is of same size.

c)It is real and inverted


4)Object is between C and Focus.

Object is between C and F
a)Image is formed beyond C.

b)It is enlarged.

c)It is real and inverted


5)Object is at focus

Object is at F
a)Image is formed at infinity.

b)It is real and inverted

c)It is highly enlarged.


6)Object is between pole and focus

Object is between P and F
a)Image is formed behind the mirror.

b)It is enlarged.

c)It is virtual and erect.

Application of concave mirror

1)Reflectors(head light,torch,search light)

2)Shaving and make up mirrors.

3)Solar cookers(When parallel beam of sunlight fall on mirror,it is brought to focus.As a result temperature increases and hence food is cooked)

4)ENT specialist uses spherical mirror.
