For the wavelength `lambda_(1)` in Young's double slit experiment seventh bright spot is situated at a distance `d_(1)` from the central bright spot. In the same experiment for the same number of bright sptot and for the different wavelength `lambda_(2)` the distance between two bright spot is `d_(2)`. Now the value of `d_(1) // d_(2)` is

Options

A. `lambda_(1)/(lambda_(2))`
B. `lambda_(2)/(lambda_(1))`
C. `lambda_(1)^(2)/(lambda_(2)^(2))`
D. `lambda_(2)^(2)/(lambda_(1)^(2))`

Answer

A
