Question

A body absorbs a photon of wavelength $\lambda$ and it emit two photons of wavelength ${\lambda }_1$ and ${\lambda }_2$. Then correct relation is:

• A. $\frac{1}{\lambda }=\frac{1}{{\lambda }_1}+\frac{1}{{\lambda }_2}$
• B. $\lambda ={\lambda }_1+{\lambda }_2$
• C. $\lambda =\frac{1}{{\lambda }_1}+\frac{1}{{\lambda }_2}$
• D. $\lambda =\frac{{\lambda }_1}{{\lambda }_2}$

Answer 1

The correct option is A $\frac{1}{\lambda }=\frac{1}{{\lambda }_1}+\frac{1}{{\lambda }_2}$

$\frac{1}{\lambda }=\frac{1}{{\lambda }_1}+\frac{1}{{\lambda }_2}$

Because the protons emit wavelength in the form of $\frac{1}{\lambda }$ and two protons are emitting so, wavelength will be ${\lambda }_1$ and ${\lambda }_2$ as $\frac{1}{{\lambda }_1}$ and $\frac{1}{{\lambda }_2}$
