Question

As temperature of a black body is raised, wavelength corresponding to maximum energy reduces. Higher temperature would mean higher energy and hence higher wavelength.

• A. Both assertion and reason are true and reason is the correct explanation of assertion
• B. Both assertion and reason are true but reason is not the correct explanation of assertion
• C. Assertion is true but reason is false
• D. Both assertion and reason are false

Answer 1

Answer: (C)

Assertion is true but reason is false

$\, \, \, \, \, \, \, \, \, \, \, \lambda_m ? \frac{1}{T}$
Hence, assertion is true but reason is false.
