In a double-slit experiment, light and dark regions are observed on a screen. What causes a dark region to be observed between two brighter regions?

Group of answer choices

Light from the two slits undergoes destructive interference.

Light from the two slits undergoes constructive interference.

The screen is inhomogeneous and absorbs light non-uniformly.

It is the shadow cast from the material in which the two slits have been made.

The two slits act like polarizing material and some of the light is blocked by the double-slits.

In Young's double-slit experiment, 632.8 nm light from a HeNe laser passes through the two slits and is projected on a screen. As expected, a central maximum (constructive interference) is observed at the center point on the screen. Now, a very thin piece of plastic with an index of refraction n=1.48 covers one of the the slits such that the center point on the screen, instead of being a maximum, is dark. Part A Determine the minimum thickness of the...

A double-slit experiment produces an interference pattern on a screen 2.8 m away from slits. Light of wavelength λ= 460 nm  falls on the slits from a distant source.

You are doing a double slit experiment with light. One slit is wider than the other, so one of the waves is stronger. There is never exact cancellation, or complete destructive interference. On a screen far away you observe a pattern of maxima and minima, and the intensity of the light in a maximum is 4 times as large as that in a minimum. What is the ratio of the widths of the two slits?

In a double-slit experiment, light with a wavelength λ passes through a double-slit and forms an interference pattern on the screen at a distance L from the slits. What statement is true for the resulting interference pattern if the frequency of the light increases? The distance between maxima increases. Not enough information given. The distance between maxima stays the same. The distance between maxima decreases.
