Physics - Wave Optics Question with Solution | TestHub

In Young's double slit experiment, the ' ${\mathrm{n}}^{\text{th ’ }}$ maximum of wavelength ' ${\lambda }_1$ ' is at a distance ' $y_1$ ' from the central maximum. When the wavelength of the source is changed to ' ${\lambda }_2$ ', ${\left(\frac{\mathrm{n}}{2}\right)}^{\text{th }}$ maximum is at ' ${\mathrm{y}}_2$ ' from its central maximum. The ratio $\frac{{\mathrm{y}}_1}{{\mathrm{y}}_2}$ is
