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 ❤
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...?
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

Most welcome 😊
very well explained sir thank you so much
Most welcome..
Well explained Sir. It helped a lot.
Thank you so much it helped a lot
Most welcome and best luck
Sir dynamic physics ke liye koi channel suggest kardo please sir
Well explained sir 👍🏻
Thanks and welcome.. keep watching..
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
Nice explanation sir👍👍
Thank you..
Thanks for uploading video sir
Welcome..
Nice explanation sir!!
Thank you..
Sir plz tell me why we kept current constant when we want to determine energy gap of semiconductor??

Busy in some other work now.. will try to do it later..
Thank you sir ❤❤
Thank you so much sir ❤️
Most welcome

ধন্যবাদ
Woww 🥰😍
Thank you 🙏
Well explained watching this before exam day can we attempt in paper sir
Watch in advance.. revise notes before exam
Thnx sir
welcome
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
