Newton in the year 1666 , also he said that colours were not introduced by the prism ,but they were components of white light.
Diffraction is the bending of the light rays at small aperture
I would guess its nothing, because technically speaking a laser uses concentrated light
Diffraction is the spreading of waves that pass through a narrow opening or move past an obstacle ,whereas, interference is the phenomenon of redistribution of light in a medium as a result of light waves from two coherent sources.
Diffraction.
diffraction
Diffraction of light waves is caused by the density of the medium through which the light is passing. Diffraction results when light travels from rarer to denser medium.
Diffraction is the tendency of light to spread around corners.

A diffraction grating does not disperse light into its component colors. However, a prism does. A diffraction grating simply causes light to diffract and display an interference pattern on a screen.
The diffraction of light in the real life can be seen as a rainbow pattern on a DVD or CD. The closely spaced tracks function as diffraction grating. A credit card's hologram is another example diffraction light application in real life. The grating structure on the card produces the desired diffraction pattern.
No. The diffraction pattern does depend on the frequency, though.
Light does not always travel in st. lines. it bends arround an obstacle if its size smaller than the wavelength of the light wave.This is called diffraction
If you shone monochromatic light on a diffraction grating it would alternate bright and dark bands. Only white light white light shone through a diffraction grating would produce a band of colors.
Diffraction means bending. Okay. Bending of what? Bending of waves. Waves may be sound wave, or waves on the surface of water and even light wave. Bending at? Bending at the sharp edges of the obstacle on the way of movement of the wave. If suppose light is not a wave then diffraction phenomenon may not be possible. The very diffraction phenomenon establishes once again that light is a wave.
