Im trying to use the RH formula but its not working out, how would you do these problems?

A highly excited atom of hydrogen makes a transition from the n = 10 to the n = 9 state and emits a photon. What is the energy of this photon in joules?

What is the wavelength in meters of the photon emitted when this highly excited hydrogen atom of hydrogen makes its transition from the n = 10 to the n = 9 state?

Can you show your work, and then we can see where you're going wrong.

E=-RH/n2
 
E1= -2.179e-18J/9^2 = -2.72375e-20
E2= -2.179e-18J/10^2 = -2.179e-20

Etotal = -4.869e-20
