How to Approach Physics Case Study Questions

Ah, the million-dollar question! How do you tackle these daunting case study questions? Let’s dive in.

Effective Reading Techniques

A vital part of cracking case study questions is understanding the problem correctly. Don’t rush through the question, take your time to fully grasp the scenario, and don’t skip over the details – they can be critical!

Conceptual Analysis

Once you’ve understood the problem, it’s time to figure out which physics principles apply. Remember, your foundational knowledge is your greatest weapon here.

Solving Strategies

Next, put pen to paper and start solving! Follow a systematic approach, check your calculations, and make sure your answer makes sense in the context of the problem.

Case Study Questions for Class 12 Physics Chapter 12 Atoms

• Last modified on: 2 years ago
• Reading Time: 3 Minutes

Case Study Question 1:

The spectral series of hydrogen atom were accounted for by Bohr using the relation

where, R=Rydberg constant = 1.097 x 10 7 m -1

Lyman series is obtained when an electron jumps to first orbit from any subsequent orbit. Similarly, Balmer series is obtained when an electron jumps to 2 nd orbit from any subsequent orbit. Paschen series is obtained when an electron jumps to 3 rd orbit from any subsequent orbit. Whereas Lyman series in U.V. region, Balmer series is in visible region and Paschen series lies in infrared region. Series limit is obtained when n 2 =∞.

(i) The wavelength of first spectral line of Lyman series is (a) 1215.4 A 0 (b) 1215.4 cm (c) 1215.4 m (d) 1215. 4 mm

(ii) The wavelength limit of Lyman series is (a) 1215.4 A 0 (b) 511.9 A 0 (c) 951.6 A 0 (d) 911.6 A 0
