mam you can become a professor in iit and nit...your's teaching skills ARE tooo good mam ..thank ypu for your lectures

[@physicsjessy7746]

Wow, thank you so much🙏

[@zb7730]

YES!!. That was clear. Just gained a subscriber. Could not understand this concept for my chemical instrumentation course previously but I have a better understanding of the differences between the 3 and 4 laser systems. Thank you Physics Jessy

[@physicsjessy7746]

Thank you too🙏
