Q1.In a spherical mirror, what is the distance of the object from its pole called?

A. image distance (v) B. focal length (f) C. object distance (u) D. radius of curvature (R)

Q2.What is the distance of the image from the pole of a spherical mirror referred to as?

A. object distance (u) B. focal length (f) C. image distance (v) D. magnification (m)

Q3.Which of the following equations correctly represents the mirror formula for spherical mirrors?

A. 1/u - 1/v = 1/f B. 1/v + 1/u = 1/f C. u + v = f D. 1/f - 1/u = 1/v

Q4.When substituting numerical values for u, v, f, and R in the mirror formula, which convention must be used?

A. The Standard International Convention B. The Right-Hand Rule Convention C. The Old European Sign Convention D. The New Cartesian Sign Convention

Q5.If 'h' is the height of the object and 'h'' is the height of the image, which formula represents the magnification 'm' produced by a spherical mirror?

A. m = h / h' B. m = h' - h C. m = h' / h D. m = h * h'

Q6.How is magnification (m) related to the object distance (u) and image distance (v) for a spherical mirror?

A. m = v/u B. m = u/v C. m = -v/u D. m = -u/v

Q7.What does a negative sign in the value of magnification indicate about the image formed by a spherical mirror?

A. The image is virtual B. The image is erect C. The image is real D. The image is diminished

Q8.For a spherical mirror, if the magnification has a positive sign, what kind of image is formed?

A. Real image B. Inverted image C. Diminished image D. Virtual image

Q9.According to the sign convention, why is the height of the object usually taken to be positive?

A. Because it is always smaller than the image B. Because it is placed below the principal axis C. Because it is usually placed above the principal axis D. Because it is always a real object

Q10.For a convex mirror used for rear-view, if an object is located at 5.00 m from the mirror and its radius of curvature is 3.00 m, what is the position of the image?

A. 1.15 m in front of the mirror B. 1.15 m at the back of the mirror C. 5.00 m in front of the mirror D. 5.00 m at the back of the mirror
