which of the six numbered feature represents emission lines?

Expert Solution & Answer
Check Mark

Answer to Problem 1VSC

Solution: feature 1.

Explanation of Solution

When an electron jumps from higher energy state to lower energy state, it emits wavelength corresponding to energy gap of the two levels. Emission spectrum corresponds to lines or peaks on a continuous background. In the given spectrum, we can see peak in the region represented by number 1.

Conclusion: Hence, the emitted lines are represented by 1 only.
