Thanks bro

[@natishm7165]

Very good lecture.Got it understood

[@s.pasupathy944]

Sir very nice explain thanks

[@kurapatipenchalasimhavishn7245]

thank you sir for ur explanation

[@aakashdewangan7313]

thankyou very much..........i am very happy for this.

I didn't get the required answer for example 5. Is the expression for phase velocity wrong?
