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.

d. A concave mirror has a focal length of 20 cm. An object is placed 30 cm in front of the mirror. Determine the position and nature of the image formed.

e. A convex mirror has a focal length of -15 cm. If an object is placed 40 cm in front of the mirror, find the position and nature of the image.

f. A concave mirror has a radius of curvature of 40 cm. Calculate its focal length.

g. An object is placed 25 cm in front of a convex mirror. The image distance is measured to be -10 cm. Calculate the focal length of the mirror.

h. A concave mirror has a focal length of 25 cm. An object is placed at a distance of 10 cm in front of the mirror. Calculate the magnification of the image formed.

{*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.}
