Assertion (A): Infrared waves are often called heat waves.
Reason (R): Infrared waves vibrate not only electrons but entire atoms or molecules.
Both (A) \(&\) (R) are true and the (R) is the correct explanation of the (A)
Both (A) \(&\) (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false
Solution:
Infrared waves are absorbed by molecules, increasing their vibrational and rotational energy, which manifests as heat. Thus, both A and R are true, and R explains A.
