Скачать или смотреть Diffraction or Interference ?

"Diffraction" a phenomenon that demonstrates wave nature of light !!!

In this Video I have tried to show in easiest manner ..in reality this is very complex and requires advanced lasers and laboratory with delicate precision.

In this Video I took single slit ..so it is basically diffraction ..
And pattern observed is with decreasing intensity from central bright fringe.
It is one of the crucial topics from wave optics .

In actual YDSE, interference takes place in which all fringes of equal brightness .

A experiment quite similar to this in which we use double slit , is popularly known as "Young's Double slit experiment
Or in short "YDSE"

Let's understand YDSE in simpler way -

In 1801 Thomas Young provided the first experimental evidence for the wave theory of light from double slit interference experiment. Young allowed the sunlight to pass a through a pin hole So on first screen followed by S1 and S2 at some distance on second screen as shown in figure. On the screen he observed few coloured bright and dark bands. To increase the brightness of bands the pin holes S1 and S2 are replaced by narrow slits and to increase the number of fringes sunlight is replaced by monochromatic source. Finally the interference pattern consists of equally spaced bright and dark fringes are obtained.

●It is due to interference of two light waves .. 😯

Any query dm me
