Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

1- Describe (in detail) the interference pattern that theory predicts would have appeared on the screen

2- Explain what the single slit does to the light source and why it must be present to the left of the double slit in order to see a clear pattern on the screen.

Some monochromatic but incoherent light was shone onto a very narrow single slit, after which it passed
through two narrow double slits and was finally project onto a screen. A schematic diagram of this set up is
shown below.

Explain the topic belows. General Conditions for Interference For sustained interference of light to occur, the following conditions must be met: 1. Coherent sources of light are needed. 2. Amplitudes and intensities must be nearly equal to produce sufficient contrast between maxima and minima. 3. The source must be small enough to produce wide fringes. 4. The interfering sources must be near enough to produce wide fringes. 5. The source and screen must be far enough to produce wide fringes. 6. The source must emit light in the same state of polarization. 7. The source must be monochromatic.
