QUESTION STATEMENT:द्विभाषी / Bilingual
निम्न विकिरण प्रकारों में से किसमें सर्वाधिक ऊर्जा होती है?
Which of the following types of radiation has the highest energy?
SELECT CORRECT OPTION:
A
दृश्य किरणों में
Visible rays
B
एक्स-रे
X-rays
Correct
C
अल्ट्रावॉयलेट
Ultraviolet
D
इन्फ्रारेड
Infrared
Official Solution & Explanation:
Correct Answer: Option B(एक्स-रे)
फोटॉन की ऊर्जा $E = h\nu = \frac{hc}{\lambda}$ होती है। दिए गए विकल्पों में एक्स-रे की तरंगदैर्ध्य सबसे छोटी होती है, अतः इसकी ऊर्जा सर्वाधिक होती है।
Since energy $E = hc/\lambda$, radiation with shorter wavelength carries greater energy. Among visible, ultraviolet, infrared, and X-rays, X-rays have the shortest wavelength and highest photon energy.
