Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.

Show Answer
Answer:
Correct Answer: C
Solution:
According to Wien’s law $ {\lambda _{m}}T $ = constant i.e., peak emission wavelength $ {\lambda _{m}}\propto \frac{1}{T}. $ Also as T increases $ {\lambda _{m}} $ decreases. Hence assertion is true and reason is true.
