C.1 ÅCorrect
D.1 kilometer
Explanation & Solution

Correct Answer: (C) 1 Å

X-rays are high-energy electromagnetic waves having wavelengths ranging approximately from 0.01 nm to 10 nm (0.1 Å to 100 Å). Thus, the characteristic wavelength of X-rays is of the order of 1 Angstrom (1 Å = 10^-10 m).

A.1 मीटर
B.1 सेमी
C.1 Åसही
D.1 किलोमीटर

सही उत्तर: (C) 1 Å

एक्स-किरणें उच्च ऊर्जा वाली विद्युत चुम्बकीय तरंगें हैं जिनकी तरंगदैर्घ्य लगभग 0.01 nm से 10 nm (0.1 Å से 100 Å) के परिसर में होती है। अतः एक्स-किरणों की तरंगदैर्घ्य की मानक कोटि 1 एंग्स्ट्रॉम (1 Å = 10^-10 m) होती है।
