Question

Problem 1

Answer 1

Given information

The light passing through the two slits is observed on a distant screen. The interference pattern observed on the screen would have the widest spaced fringes.

Step-by-step explanation

Step 1.

When the widths of the slits are significantly greater than the wavelength of the light, the rules of geometrical optics hold the light casts two shadows, and there are two illuminates regions on the screen.

However, the slits are narrower in width, the light diffracts into the geometrical shadow, and the light waves overlap on the screen.
