Question

ASSERTION - Black body is an ideal body that emits and absorbs radiation of all frequencies. REASON- The frequency of radiation emitted by a body goes from a lower frequency to higher frequency with an increase in temperature. *
Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.
The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.
