8:22 sir in fraunhofer diffraction if source and screen is kept at infinite distances how are we able to observe and make measurements

[@EngineeringPhysicsbySanjiv]

That's why we are using convex len between source and slit. When we keep source at focal point, after refraction through lens, we get light waves similar to the waves coming from infinity.. One more lens is kept between the slit and the screen.. this helps in converging the light waves at finite distance where we keep screen and observe the pattern..

@@EngineeringPhysicsbySanjiv oh yeah right ! Thanks for replying sir

[@ssekandumicheal209]

Thank you so much for that wonderful lecture.However, in the first example I am getting the first position of the first angular minimum as 26.198 degree instead of 23.57degrees.

So nice of you.. Thank you and best luck to you..

[@omparghale]

sir, how is condition for minimum asinθ=nλ shouldnt it be asinθ=(2n+1)λ/2 as we are talking about minimum which means dark band which in turn means they are out of phase, and as we know out of phase corresponds to (2n+1)λ/2. Please clarify sir.

[@EngineeringPhysicsbySanjiv]

For, asinθ=nλ, resultant amplitude is zero. so intensity will be zero.

[@Computergeek-zw3go]

that was in double slit experiment when initial phase difference bw waves is 2npi

[@sayedmariya9636]

Sir what is the difference between diffraction grating and transmission grating???

[@EngineeringPhysicsbySanjiv]

I think this question is already answered.. Diffraction grating can be used as a reflection grating or transmission grating. If we get diffraction pattern on the same side from where the light waves are incident, then we are using grating as reflection grating. If we make light rays incident from one side and get diffraction pattern on the other side, means grating is used as a transmission grating..
