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 ' ${\mathrm{Y}}_1$ ' from the central maximum. When the wavelength of the source is changed to ' ${\lambda }_2$ ', $5^{\text{th }}$ maximum is at a distance ' $Y_2$ ' from the central maximum. The ratio $\frac{{\mathrm{Y}}_1}{{\mathrm{Y}}_2}$ is
