Physics - Wave Optics Question with Solution | TestHub

In Young's double slit experiment, the $10^{\text{th }}$ maximum of wavelength ${\lambda }_1$ is at a distance of $y_1$, from the central maximum. When the wavelength of the source is changed to ${\lambda }_2,5^{\text{th }}$ maximum is at a distance of $y_2$ from its central maximum. The ratio $\left(\frac{{\mathrm{y}}_1}{{\mathrm{y}}_2}\right)$ is
