Question

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 = 2λ2 (B) λ1 = 4λ2 (C) λ1 = (1/2)λ2 (D) λ1 = λ2

Tardigrade Admin · Accepted Answer

E1=25 eV , E2=50 eV E1=(h C/λ1) and E2=(h c/λ2) or (E1/E2)=(λ2/λ1) or (25/50)=(λ2/λ1) or λ1=2 λ2

Q. The energies $E_{1}$ and $, E_{2}$ of two radiations are $25 e V$ and $50 e V$ respectively. The relation between their wavelengths, i.e. $λ_{1}$ and $λ_{2}$ will be

$λ_{1} = 2 λ_{2}$

$λ_{1} = 4 λ_{2}$

$λ_{1} = \frac{1}{2} λ_{2}$

$λ_{1} = λ_{2}$

$E_{1} = 25 e V, E_{2} = 50 e V$
$E_{1} = \frac{h C}{λ _{1}}$ and $E_{2} = \frac{h c}{λ _{2}}$
or $\frac{E _{1}}{E _{2}} = \frac{λ _{2}}{λ _{1}}$
or $\frac{25}{50} = \frac{λ _{2}}{λ _{1}}$
or $λ_{1} = 2 λ_{2}$

Q. The energies E1​ and ,E2​ of two radiations are 25eV and 50eV respectively. The relation between their wavelengths, i.e. λ1​ and λ2​ will be

λ1​=2λ2​

λ1​=4λ2​

λ1​=21​λ2​

λ1​=λ2​
