At the science lab, the absorption spectrum for atomic hydrogen shows black lines at wavelengths of 486 nm and 656 nm. What would you expect to see in the absorption spectrum for atomic hydrogen emitted by an object that is moving toward you?

A. A redshift with black lines at wavelengths higher than 486 nm and 656 nm
B. A blueshift with black lines at wavelengths lower than 486 nm and 656 nm
C. A redshift with black lines at wavelengths lower than 486 nm and 656 nm
D. A blueshift with black lines at wavelengths higher than 486 nm and 656 nm

The absorption spectrum for atomic hydrogen emitted by an object moving toward you would exhibit a blueshift with black lines at wavelengths lower than the original 486 nm and 656 nm.

Explanation:

Blueshift is observed in the absorption spectrum for atomic hydrogen emitted by an object moving toward you. In this scenario, the black lines at wavelengths would be lower than 486 nm and 656 nm, indicating a blueshift with wavelengths lower than the original values.
