frostbite · Answer

One way would be to use the Rydberg formula for hydrogen.

anonymous · Answer

oh.. whats that? :(
i know these formula, 
c=(lamda) f
and the formula for change in energy, cant i solve it using these? :(

anonymous · Answer

another is Ephoton = hv

frostbite · Answer

Hmmmm I would perhaps more use this:
$$\frac{ 1 }{ \lambda }=R \left( \frac{ 1 }{ n _{1}^{2} } - \frac{ 1 }{ n_{2}^{2} } \right)$$

frostbite · Answer

This equation can calculate any wavelength due to jumps between the shells in hydrogen.

anonymous · Answer

$$R= -2.178 x 10^{-18}$$

anonymous · Answer

what do you call that equation?

frostbite · Answer

the Rydberg formula

oh thank you so much :)
