Assertion: Two sources of equal intensity always emit equal number of photons in any time interval.
Reason: Two sources of equal intensity may emit equal number of photons in any time interval.
Reason: Two sources of equal intensity may emit equal number of photons in any time interval.
View answer and explanation
Correct option: D
Assertion is incorrect, reason is correct.
Option D is correct because the assertion is false, as intensity depends on both the number of photons and their energy, while the reason is true as equal intensity does not guarantee an equal number of photons due to frequency differences.
