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.
- If both Assertion 'and Reason are correct and Reason is the correct explanation
- If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion
- If Assertion is correct but Reason is incorrect
- If Assertion is incorrect but Reaso
Correct answer: If both Assertion 'and Reason are correct and Reason is the correct explanation
Solution
The assertion is true because for mirrors inclined at 60°, the number of images is determined by the successive-reflection formula. Since 360/60 = 6, which is even, the image count is 6 - 1 = 5, so the reason correctly explains the assertion.
