Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the difference between emission and absorption spectra?

  • Emission spectra show emitted light while absorption spectra show light that is absorbed.
  • Emission spectra show absorbed light while absorption spectra show emitted light.
  • There is no difference
  • they are the same.

💡 Hint: Think about how each type of spectrum is produced.

Question 2

True or False: The flame color of an element can be used to identify that element.

  • True
  • False

💡 Hint: Recall our discussion about flame tests.

Question 1

Explain how the Rydberg formula can be used to predict the wavelengths of spectral lines in hydrogen and provide an example of its application.

💡 Hint: Consider how the values of n affect the resulting wavelength.

Question 2

Using knowledge of the Stark Effect, discuss how external electric fields could manipulate atomic spectra and what that implies for real-world applications.

💡 Hint: Think about how real-world electric fields might impact photon energies.
