Mirror Formula and MagnificationQuiz - Solve & Score
Q1. The magnification produced by a plane mirror is +1. What does this mean?
- A.The image is real and inverted
- B.The image is virtual and erect
- C.The image is real and erect
- D.The image is virtual and inverted
Answer: B. The image is virtual and erect
What's the underlying rule? The image is virtual and erect. Does that line up with one of the options? Yes - This is the correct meaning of magnification +1. And the rest? option A) 'The image is real and inverted' misses the point - Plane mirrors produce erect images; option C) 'The image is real and erect' is wrong because Plane mirrors produce erect images. Pick: B) The image is virtual and erect.
Q2. If the object is at the centre of curvature of a concave mirror, the magnification is (NCERT):
- A.-1
- B.+1
- C.-2
- D.+2
Answer: A. -1
Start by listing the data - the numerical data stated in the question (physics, chapter 'Light - Reflection and Refraction'). Our target: the unknown asked. From the chapter we use the relation: hence the answer = -1. The arithmetic is: hence the answer = -1. An ionic bond forms when a metal donates electrons to a non-metal: e.g. So the correct choice is A) -1. As for the others, option B) '+1' misses the point - It is real inverted same-size => m = -1; option C) '-2' doesn't hold - Same size means |m| = 1, so m = -1.
Q3. In the mirror formula, u is the:
- A.object distance from the pole
- B.focal length
- C.image distance
- D.radius of curvature
Answer: A. object distance from the pole
