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.

  1. If both Assertion 'and Reason are correct and Reason is the correct explanation
  2. If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion
  3. If Assertion is correct but Reason is incorrect
  4. 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.
