Section A

1. Fill in the blanks: (5 Marks)

a. The laws of reflection state that the incident ray, the reflected ray, and the _______ to the surface at the point of incidence, all lie in the same plane.

b. In a concave mirror, when the object is located between the pole and the ________, a virtual and enlarged image is formed.

c. The ________ of a spherical mirror is the point on the principal axis where parallel rays of light converge or appear to diverge from.

d. In a convex mirror, the image formed is always ________, virtual, and smaller in size compared to the object.

e. The mirror formula for a concave mirror is given by 1/f = 1/v - ________, where 'f' is the focal length, 'v' is the image distance, and 'u' is the object distance.

Section B

2. Short Answer Type Questions: (1 Marks Each)

a. Explain the difference between a plane mirror and a spherical mirror.

b. What are the different types of spherical mirrors?

c. Define the term "radius of curvature" of a spherical mirror.

d. Explain the meaning of "focal length" in relation to spherical mirrors.

e. State the relationship between the radius of curvature and the focal length of a spherical mirror.

3. Long answer type Questions: (3 marks each)

a. Define reflection and state the laws of reflection.

b. State the sign conventions used in spherical mirrors.

c. Explain the terms "pole," "principal axis," and "focus" in the context of a spherical mirror.

d. What is a virtual image? How is it formed by a spherical mirror?

e. Describe the formation of a real image by a concave mirror.

f. State the uses of concave and convex mirrors in daily life.

Section C

4. Numerical-Based Questions: (4 marks each)

a. An object is placed at a distance of 20 cm from a concave mirror. If the focal length of the mirror is 15 cm, determine the position and nature of the image formed.

b. A convex mirror has a focal length of -10 cm. If an object is placed 20 cm in front of the mirror, find the position and nature of the image.

c. Define magnification and calculate the magnification of an image formed by a concave mirror when the object distance is 10 cm and the image distance is -15 cm.

{*Please note that these numerical problems may require the use of the mirror formula (1/f = 1/v - 1/u) and the magnification formula (m = -v/u), where 'f' is the focal length, 'v' is the image distance, and 'u' is the object distance.}
