MCQ

Assertion (A): Energy of radiation is large if its wavelength is large.
Reason (R): Energy $= h \nu\left(\nu=\right.$ frequency, $\left.\nu=\frac{c}{\lambda}\right)$

A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
✓
A is false but R is true.

✓

Answer

Correct option: D.

A is false but R is true.

(d) A is false but R is true.
Explanation: Energy of radiation is small if its wavelength is large
$\because E =\frac{h c}{\lambda}$ (inverse relationship between E and $\lambda$ ).
