t=e^(-2aL)

a is a=sqrt(m*(u-e)/hbar

 

if m is dobouled how would i write the t= equasion?

is is t=e^(-2*2a^1/2 L)

i know its wrong im just so confused

if m is doubled then

 

t=e2aL

 

would still be written the same way!  However, 'a' would be different.  So if we use 'a' for the original and 'a2' for  when m is doubled then we could write:

 

t=e2a2L

 

or

 

t=e22aL

Melody, hbar is Planck's constant h divided by 2pi and is usually written with the bar crossing the upright of the h rather than being above the h, thus:
