Challenge Problems
Push your limits with challenges.
Question 1
You observe a series of emission lines for an element that falls in the visible spectrum at wavelengths 450 nm and 500 nm. Calculate the energy required for an electron transition that results in the emission of these photons.
💡 Hint: Remember to convert wavelength from nanometers to meters first.
Question 2
Explain the phenomenon observed when light from a distant star shows absorption lines in its spectrum. What does this tell us about the star's composition?
💡 Hint: Think about how light interacts with atoms and what that means for identifying elements.
