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.

please draw diagrams, show all work, I will report if you copy off chegg, please explain throughly thank you! You are designing a diffraction grating, and have decided that when the grating is used with a white light source, both the entire first and second order rainbows (visible part of the spectrum) should be visible within 30° of the central maximum. In order to have the machine shop produce your grating, you need to calculate the line density of the grating. You also wonder how many complete rainbows could potentially be seen with this grating. Your textbook says that the visible light has wavelengths between 400 and 700 nm.

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.
