7. A point object is placed at a distance of 20 cm from a convex mirror of focal length 20 cm. The image will form at:

a .at infinity

b .at focus

c .at the pole

d. behind the mirror

 ANSWER THE FOLLOWING CONCEPTUAL QUESTIONS-

1. If the image formed by mirror for all positions of the object placed in front of it is always virtual and diminished, state the type of the mirror. Draw a ray diagram in
support of your answer. Where are such mirrors commonly used and why?

2. With the help of ray diagrams, show the formation of images of an object by a concave mirror. When it is placed

(i) beyond the center of curvature (ii) at the center of curvature.

3. Draw ray diagrams to show the formation of image by an object by a concave mirror when the object is placed

(i) at Centre of curvature (ii) between pole and focus .

4. A student has three concave mirrors A, B and C of focal lengths 20 cm, 15 cm and 10 cm respectively. For each concave mirror he performs the experiment of image formation for three values of object distance of 30 cm, 10 cm and 20 cm.

Giving reason answer the following:

a. For the three object distances, identify the mirror which will form an image equal in size to that of object. Find at least one value of object distance.

b. Out of the three mirrors, identify the mirror which would be preferred to be used for shaving purpose.

c. For the mirror B, draw ray diagram for image formation for any two given values of object distance.

5. Why do we prefer a convex mirror as a rear- view mirror in vehicles?

6. a) Which mirror is used by dentists?

7. Name the type of mirror used in following situations

i. Headlights of the car

ii. Side/rear view mirror of a vehicle

iii. Solar furnace

8. A spherical mirror produces an image of magnification -1 on a screen placed at a distance of 50 cm from the mirror.

(a) Write the type of mirror.

(b) Find the distance of the image from the object.

(c) What is the focal length of the mirror?

(d) Draw the ray diagram to show the image formation in this case.

 ANSWER THE FOLLOWING NUMERICALS-

1. 4.5 cm needle is placed 12 cm away from a convex mirror of focal length 15 cm. Give the location of image and magnification. Describe what happens to the image as the needle is moved farther from the mirror.

2. Rohit placed a pencil perpendicular to principal axis in front of a converging mirror of focal length 30 cm. The image formed is twice the size of the pencil. Calculate the distance of the object from the mirror.

3. Find the size, nature and position of image formed when an object of size 1 cm is placed at a distance of 15 cm from concave mirror of focal length 10 cm.

4. An object is placed at a distance of 10cm in front of convex mirror of focal length 15cm. find the nature and position of image.

5. An object 2 cm high is placed at a distance of 16 cm from a concave mirror which produces a real image 3cm high.

(a) Find the position of the image

(b) What is the focal length of mirror?

6. An object placed 15 cm in front of a lens forms a real image three times magnified. Where is the image formed? What is the focal length of the lens?

7. An object 3 cm high is placed at a distance of 9 cm in front of a concave mirror of focal length 10 cm. Find the position, nature and size of the image formed.
