The variation of maximum intensity (Em) of radiation with temperature ...
Explanation:
The maximum intensity (Em) of radiation emitted by a blackbody at a given temperature is given by Wien's displacement law as:

Em = b/T

where b is a constant known as Wien's displacement constant.

Therefore, the variation of maximum intensity (Em) of radiation with temperature (T) is proportional to 1/T.

However, if we express the temperature (T) in terms of its reciprocal (1/T), we get:

Em = b/(1/T) = bT

Therefore, the variation of maximum intensity (Em) of radiation with temperature (T) is directly proportional to temperature (T).

Hence, the correct option is (1) T.

Summary:
- The maximum intensity (Em) of radiation emitted by a blackbody at a given temperature is given by Wien's displacement law as Em = b/T, where b is a constant known as Wien's displacement constant.
- The variation of maximum intensity (Em) of radiation with temperature (T) is proportional to 1/T.
- However, if we express the temperature (T) in terms of its reciprocal (1/T), we get Em = bT, which shows that the variation of maximum intensity (Em) of radiation with temperature (T) is directly proportional to temperature (T).
- Hence, the correct option is (1) T.
