vibration frequency in wave number

[sanan...@gmail.com]

Hi,

I have a question about what is happening in this video at 00:13:47 -

http://www.youtube.com/watch?v=-iQwimBxKRg#t=827s.

vibration frequency wave no: is shown as 1/(2*pi* c) * sqrt(k/mu). But as per previous lecture it should be 1/(2* pi h*c)*sqrt(k/mu). I guess h is missing.

Thanks!

Dear Student,

The vibration frequency wave number will be  1/(2*pi* c) * sqrt(k/mu). Could you please let me know in which previous lecture it is mentioned as  1/(2* pi h*c)*sqrt(k/mu). I'll be able to solve your doubt then.
