i am given this equation
View attachment 2323
where L is the rod of length when light signals are applied at one end (x=0)
D>0 is the diffusivity T>0 a time constant, A amplitude of the applied signal(carriers per second), g(t) the oscillatory behavior of the signal and α> 0 a material constant.
i need to change the equation above into one where all the symbols are dimensionless.
where
T is taken as the unit time
α^-1 the unit of length
AT the carrier density.
i am given that
the new dependent variables q=q(y,τ) is defined TAq(y, τ)= p(y/α,Tτ)
my work
from the above information, i defined new dimensionless independent variables
τ(tau) := t/ T(time)
y:= αx(position)
now how do i verify that the equation below is dimensionless and explain the symbols d and h(τ)
