RE-NEET 2024 Chemistry Spectral Lines Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 11

Given below are two statements: Statement I: The Balmer spectral line for H atom with lowest energy is located at 536RH cm1\frac{5}{36} R_H \text{ cm}^{-1}. (R_H = Rydberg constant) Statement II: When the temperature of blackbody increases, the maxima of the curve (intensity of wavelength) shifts to shorter wavelength. In the light of the above statements, choose the correct answer from the options given below:

A

Statement I is true but Statement II is false.

B

Statement I is false but Statement II is true.

C

Both Statement I and Statement II are true.

D

Both Statement I and Statement II are false.

Correct Answer

Option C

Detailed Explanation

Statement I is correct as the Balmer series starts at 536RH cm1\frac{5}{36} R_H \text{ cm}^{-1}. Statement II is true as Wien's displacement law states that the peak wavelength decreases as temperature increases.
