Construction and working of a Ruby laser Which type of pumping used in Ruby laser? Why cooling mechanism is needed in Ruby laser? Why Ruby laser can not be operated in continuous mode?
Thanks sir tomorrow my mod sem exam paper of physics and I don't understand the ruby laser in my class but I will see your video and I will understand and sir your explanation is very simple. So thank you sir ❤
Respected sir kya aap statical physics ke bus besic vidio upload kar sakte hai aap ke explanation amazing hote hai bus sir aap thoda sa help kar dijiye phir hum book se bhi padh lenge please sir
I think your question s not related to this video. As I understand it is in regard of four probe experiment to determine resistivity and energy gap of semiconductor. In Four Probe experiment, the voltage across the inner two probes is noted at different temperatures. This voltage can be used to calculate resistivity when V is proportional to resistance which is possible only when current is constant. This is why a constant current is necessary.
@@EngineeringPhysicsbySanjiv no sir i m student of msc physics...we have experiment to determine enegy gap of semiconductor using potentiometer on different two different temperatures...?

Tqq soo much sir tmrw is my sem exam ur video is helpful. for me. U gave a good explanation to understand. Tqq so much🎉
All the Best👍👍
Short and sweet explanation ❤
Thank you.. best luck to you
Best explanation on RUclips
Thank you

Most welcome 😊
Thanks for such a good explanation
very well explained sir thank you so much
Most welcome..
Really ur explanation made me easy to understand Thanku sir👏🥰
Thank you so much it helped a lot
Most welcome and best luck
Well explained sir 👍🏻
Thanks and welcome.. keep watching..
Nice explanation sir👍👍
Thank you..
Can you suggest some good book of Engineering Physics with MCQs?
Engineering Physics MCQ Book by H. J. Sawant, S. V. Arlikar, Sadhana Sawant, S. S. Joshi, A. A. Sakurkar, Dr. Sanjay K. Baber
Navneet Gupta, SK Tiwary
Well explained Sir. It helped a lot.
Respected sir kya aap statical physics ke bus besic vidio upload kar sakte hai aap ke explanation amazing hote hai bus sir aap thoda sa help kar dijiye phir hum book se bhi padh lenge please sir
Busy in some other work now.. will try to do it later..
Nice explanation sir!!
Thank you..
Well explained watching this before exam day can we attempt in paper sir
Watch in advance.. revise notes before exam
Sir pl continue uploading Physics videos for MU Semister 2
Already available.. Please check the links in the following pdf -

Thanks for uploading video sir
Welcome..
Thank you sir
Most welcome
Sir dynamic physics ke liye koi channel suggest kardo please sir
Sir plz tell me why we kept current constant when we want to determine energy gap of semiconductor??

Sir what is active material in Ruby laser..... Sir plese bta dijiye
Cromium ions are active centres. In Al2O3, some Al ions are replaced by Cromium ions
@@EngineeringPhysicsbySanjiv sir ... lekin mere class me bataya gya tha ki.... Xenon coilled flash lamp hoga .... To mughe confusion h .....
Sir to chromium ion hi correct h ???
Xenon lamp is used for pumping cromium ions to excited levels
