In a Young's double slit experiment the intensity at a point is $$I$$ where the corresponding path difference is one sixth of the wavelength of light used. If $$I_0$$ denotes the maximum intensity, the ratio $$\frac{I}{I_0}$$ is equal to

A

$$\frac{1}{4}$$

B

$$\frac{1}{2}$$

C

$$\frac{\sqrt{3}}{2}$$

D

$$\frac{3}{4}$$
