Numerical on newton''s ring experiment, Physics

Q. In a Newton's ring experiment, the wavelength of the light used is 6 × 10-5 cm and the difference of square of diameters of successive rings are 0.125 cm3. What will happen to this quantity if:

(i)      The wavelength of light is changed to 4.5 ×10-5 cm.


Soln. Given: 6 × 10-3 cm

            Difference of square of diameters of successive rings D2n+1 - D2n = 0.125 cm3.
