Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

100%

A dark band in a double-slit interference pattern happens when
light from both slits reach the screen at in phase with one another (crest-to-crest
or trough-to-trough) creating constructive interference.
light from both slits reach the screen at in phase with one another (crest-to-crest
or trough-to-trough) creating destructive interference.
light from one slit reaches the screen at crest and light from the other slit
reaches the screen at trough creating destructive interference.
light from one slit reaches the screen at crest and light from the other slit
reaches the screen at trough creating constructive interference.

The diagram below shows two intensity patterns. The graph on the left shows the
intensity for light passing through a single slit. The graph on the right shows the
intensity pattern for two identical slits, each the same width as the one used to
create the first graph.
Single Slit
Double Slit
In this case, the first order minimum of the single slit pattern is at the same point on
the screen as
the third order maximum of the double-slit pattern
the central maximum of the double-slit pattern
the fifth order maximum of the double-slit pattern
the first order maximum of the double slit pattern

In a double-slit experiment, the slit separation is 2.0 mm, two wavelengths of 910 nm and 650 nm illuminate the slits, the screen is placed 2.8 meters away from the slits. At what distance from the central maximum on the screen will a dark fringe from one pattern first coincide with a dark fringe from the other?
Which of the following accurately explains why thin-film interference occurs? Some of the light reflects off the outer surface, some off the boundary between materials, leading to a path difference. Peaks and troughs then interfere with each other to produce minima and maxima. All the light reflects off the boundaries between the materials. Peaks and troughs then interfere with each other to produce minima and maxima. Oil and water undergo a chemical reaction which produces rainbow colors. Light goes through two slits, interfering to produce minima and maxima.
