NEET Chemistry Quantum Mechanical Model Assertion Reason Question
Assertion (A): The wavenumber is commonly expressed in cm⁻¹. | Reason (R): Wavenumber is defined as the number of wavelengths per unit length.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion is true as wavenumber is commonly used in cm⁻¹, but the reason does not explain this fact. The reason correctly defines wavenumber but does not relate to why cm⁻¹ is commonly used.
