AIPMT PRELIMS 2011 Physics Wavelength and Frequency MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The energies E₁ and E₂ of two radiations are 25 eV and 50 eV respectively. The relation between their wavelengths i.e. λ₁ and λ₂ will be
A
λ₁ = 1/2 λ₂
B
λ₁ = λ₂
C
λ₁ = 2λ₂
D
λ₁ = 4λ₂
Correct Answer
Option C
Detailed Explanation
Since energy is inversely proportional to wavelength, λ₁ = 2λ₂ for E₁ = 25 eV and E₂ = 50 eV.
