यह पाया गया है कि तत्वों के लाक्षणिक \(\mathrm{X}\)-किरण स्पेक्ट्रा नियमितता प्रदर्शित करते हैं। जब उत्सर्जित \(\mathrm{X}\)-किरणें की आवृति घात ' \(\mathrm{n}\) ' अर्थात \(v^{\mathrm{n}}\) को परमाणु क्रमांक ' \(\mathrm{Z}\) ' के सापेक्ष प्लॉट किया, जाता है तों निम्न ग्राफ प्राप्त होता है। \('n'\) का मान है:

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
