Spectroscopy - Postlab

Question #1




The above emission spectrum was done on a spectroscope similar to the one used in the rest of this experiment. It is one of the elements you examined.

a. Which element is it?

b. Approximate the energy associated with the green line shown in the spectrum?

c. Is the energy associated with the green line more or less than the energy associated with the yellow line?

d. A particular element is known to have an emission line resulting from the transition between two levels with an energy difference of 4.0 x 10-19 joules. Could the above spectrum belong to the element?
