@Shinaya Mendes 1st he asked about the aims of my today's experiment. Then, he told me to draw the graph for forward and reverse bias Then, he asked what is knee voltage? Then, what is dispersion? Then, what is angle of deviation?
Thx Sir, I have a practical today. Thx Edit: till date I never understood where and how pins were to be attached. Thanks to you Sir, I am able to understand it now.
Aim: To determine angle of minimum deviation for a given prism by plotting a graph between angle of incidence and angle of deviation. Materials: pencil, sheet, glass prism, scale , protractor, pins Procedure: 1) Fix the sheet with the help of pins on the table. 2) Remove the prism and draw incident ray at an angle of say 30°, with respect to the normal. 3) Fix two pins on the incident ray with some distance between them. 4) Now while looking the pins through the prism, fix two more pins where emergent ray will come from prism. All the four pins must lie at a straight line. Join the four points where pins were fixed. 5) Using protractor measure the angle between incident and emergent ray which is angle of deviation. 6) Repeat the above steps for different angles of incidence and find agle of deviation for them. Precautions: 1) While tracing the boundaries of prism on sheet, the sheet should not move. 2) Angle of incidence should be drawn wrt normal. 3) While fixing the pins of emergent ray, all the pins should lie at the same straight line. Sources of error: 1) The pins may not be in a straight line which will give wrong results.
Sir I have prepared for my boards practical from your videos only. Thank you so so so much. These are really very very helpful. Much love and respect ❤️🙏
Thnxs sir my practical is on day after tomorrow. I am a non attending student but even in my school they haven't ever talked about practical, they haven't taught but still taking exams and in this case it's just u who helped me. No words to pay gratitude.
Wowo incredible sir...some time I was trying to experiment but failed now when I am watch your video i am understanding easily 🙂...nice explanation......
2022-23 batch so glad I got to clear my small doubts I have viewed all your cbse practicals video good to see teacher like you in online platform letting us revise in just small video much appreciated 😊
Sir thank you for all these experiments . Aim:- To find the value of v for different value of u in case of a concave mirror and to find its focal length . Please cover this topic also . Please, please please...
Sir I have one doubt It would be very helpful if you would tell 🙏 In my case inspite of changing angle of incidence every time ...my angle of deviation is remaining the same i.e 40° only... Just in one case it has become 42° otherwise nowhere else So sir could you please tell is there any problem in this ?
I have my practical exam tomorrow and I'm here right now. School mei bas ek baar hi kiya tha yeh exp. and mai bhool gayi thi ki kaise karna h. Thank you so much sir for this awesome video.
@@nehassaini256 Mera viva accha gaya. Sirf tumhe jo exp. mile hai, unse hi questions puchenge. Tumhe theory se sab definitions jaise angle of minimum deviation, dispersion, laws of refraction aur wheatstone bridge principle acche se yaad hona chahiye. Phir sources of error and precautions related to every exp. padhkar jaana. Aise sawaal hi pucha gaya tha. Hope this helps. Good luck to you!

Bhai 2 hrs baade practical he aur pure saal nhi padha ab padh raha hu 💀💀
Kesa gya practical ??
Wow maje dila diya jo koi nahi samjha paya aapki 10second video me aa gaya
Sir I have one doubt
It would be very helpful if you would tell 🙏
In my case inspite of changing angle of incidence every time ...my angle of deviation is remaining the same i.e 40° only...
Just in one case it has become 42° otherwise nowhere else
So sir could you please tell is there any problem in this ?
THANK YOU SIR.
