Numericals based on lasers

[@anirbandey6206]

The first numerical really helped sir. Thanks

1:40 Sir shouldn't be e^ (+E2-E1)/kT?

[@NataNata-ur5bf]

No.. The formula itself is e^(-E/KT) Now put E2-E1 in place of E it becomes e^-(E2-E1)/KT

[@Sarvesh_7siu]

sir how to calculate e power something

[@EngineeringPhysicsbySanjiv]

Use scientific calc

[@shauryapatel2304]

Thank you sir...🙏🙏 Good numericals and nicely explained. Got to learn something new.

How to remove the e power and used logarithmic

[@EngineeringPhysicsbySanjiv]

You can rearrange the equation. But to calculate N2/N1 we need to use e power..

[@sherozali100]

sir please tell me the book which you used in this lecture

[@EngineeringPhysicsbySanjiv]

taken from university exam. You can refer to Modern Engineering Physics by SL Gupta and Sanjiv Gupta,,
