To solve the problem step by step, we will use the relationship between the number of fringes and the wavelength of light in Young's double-slit experiment. ### Step 1: Understand the relationship between the number of fringes and wavelength In Young's experiment, the number of visible fringes (n) is inversely proportional to the wavelength (λ) of the light used. This can be expressed mathematically as: \[ n \propto \frac{1}{\lambda} \] This means that if the wavelength decreases, the number of visible fringes increases, and vice versa. ### Step 2: Set up the equation using the given data ...
