toppr Q Type your question. mirrors, then 5 images of the object will be formed. Reason: For a given system of mirrors the total number of images formed due to successive reflection is equal to either \( \frac{360^{\circ}}{\theta} \) or \( \frac{360^{\circ}}{\theta}-1 \) accordingly as \( \frac{360^{\circ}}{\theta} \) is odd or even respectively.
- A. If both Assertion 'and Reason are correct and Reason is the correct explanation
- B. If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion
- C. If Assertion is correct but Reason is incorrect
- D. If Assertion is incorrect but Reaso
Step-by-step solution
The assertion that two mirrors at 60° produce 5 images is correct (since 360/60 = 6, even, number = 6-1 = 5). However, the reason given is oversimplified; the formula for number of images depends on object placement when 360/θ is odd. Therefore, the reason is incorrect as a general statement.
