# Find Tmin for J=1 to J=0 and J=2 to J=1

1. Find Tmin (minimun temp) for J=1→J=0 and J=2→J=1

2. I was given the equation, Tmin=√h(J+1)/2k

3. This is probably really simple, but I don't understand the J=1→J=0 and in the equation there is only one J. I'm just not sure what to do, any help would be nice! Thank you!
