Equation of SHM - NEET Physics Questions

Question 51: easy

Assertion (A): Vibration of polyatomic molecules is not simple harmonic motion.

Reason (R): The vibrations are superposition of SHMs of different frequency.

1. Both (A) & (R) are true and the (R) is the correct explanation of the (A)

2. Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

3. (A) is true but (R) is false

4. Both (A) and (R) are false

View Answer

Vibration of polyatomic molecules involves multiple normal modes, each with a different frequency. The total vibration is a superposition of these individual SHMs.
This complex, multi-frequency nature means the overall motion is not a single SHM. Both A and R are true, and R explains A.
