Question

Which of the following transitions have minimum wavelengths? (A)  n4→ n1  (B)  n2→ n1  (C)  n4→ n2  (D)  n3→ n1

E=(hc/λ ) or E propto (1/λ ) Thus a decrease in wave length represents an increase in energy For n4 xrightarrown1, transition. These are greater the energy difference and lesser will be wavelength. Thus, for n4 xrightarrown1 transition has minimum wavelength

Q. Which of the following transitions have minimum wavelengths?

$n_{4} \to n_{1}$

$n_{2} \to n_{1}$

$n_{4} \to n_{2}$

$n_{3} \to n_{1}$

$E = \frac{h c}{λ}$ or $E \propto \frac{1}{λ}$ Thus a decrease in wave length represents an increase in energy For $n_{4} n_{1},$ transition. These are greater the energy difference and lesser will be wavelength. Thus, for $n_{4} n_{1}$ transition has minimum wavelength

Q. Which of the following transitions have minimum wavelengths?

n4​→n1​

n2​→n1​

n4​→n2​

n3​→n1​

E=λhc​ or E∝λ1​ Thus a decrease in wave length represents an increase in energy For n4​​n1​, transition. These are greater the energy difference and lesser will be wavelength. Thus, for n4​​n1​ transition has minimum wavelength

$n_{4} \to n_{1}$

$n_{2} \to n_{1}$

$n_{4} \to n_{2}$

$n_{3} \to n_{1}$

$E = \frac{h c}{λ}$ or $E \propto \frac{1}{λ}$ Thus a decrease in wave length represents an increase in energy For $n_{4} n_{1},$ transition. These are greater the energy difference and lesser will be wavelength. Thus, for $n_{4} n_{1}$ transition has minimum wavelength
