What happens when you add more slits?

Increasing the number of slits not only makes the diffraction maximum sharper, but also much more intense. As the intensity increases, the diffraction maximum becomes narrower as well as more intense.

What is the separation of the two slits?

The diffraction pattern of two slits of width D that are separated by a distance d is the interference pattern of two point sources separated by d multiplied by the diffraction pattern of a slit of width D. and used the integer m to refer to interference fringes.

Are there any points between the maxima of the original two slits where light from all three slits interferes constructively if so what are they?

If so, what are they? Since the original two slits do not interfere constructively anywhere except for the original maxima, it would be impossible for all three slits to interfere constructively somewhere between the original maxima.

Which behavior of light does the double-slit experiment demonstrate?

In modern physics, the double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena.

How do you find the distance between two slits?

In my book’a section on Young’s double-slit experiment, the formula, d=mλsinθ, is given. In this equation d is the distance between two slits, λ is the wavelength of light coming through the slits, and θ is the angle between the central reference to the brightest maximum on the screen opposite the slits.

Why does light passing through two narrow slits create an interference pattern?

When monochromatic light passing through two narrow slits illuminates a distant screen, a characteristic pattern of bright and dark fringes is observed. This interference pattern is caused by the superposition of overlapping light waves originating from the two slits.

What happens to the two slit interference pattern if the separation between the slits is less than the wavelength of light?

In YDSE, if separation between the slits is less than wavelength of light, then no interference pattern can be observed.
