### Homework number 1.25a

Why is the power of the final answer -19? I keep getting a different result every time I repeat the calculation.

Too find the energy emitted by the photon you use the formula: E=hc/wavelength
First: convert wavelength from nanometers to meters (589*10^-9)
Then plug it into the equation: (6.626*10-34)(3*10^8)/(589*10^-9)
Energy= 3.37*10^-19
