_____________________light is the only type of EM wave detected by the human eye.

• Red
• Gamma
• Microwave
• Visible

Emission of light from an atom occurs when an electron

• drops from a higher to a lower energy level.
•    jumps from a lower to a higher energy level.   
•    moves within its atomic orbital.
• falls into the nucleus.

The splitting of white light into a spectrum is called...

• diffraction
• dispersion
• divergence
• refraction

The emission spectrum is caused by

• the gas absorbing photons of certain frequencies as electrons move down energy levels

• the gas emitting photons of certain frequencies as electrons move up energy levels

• the gas emitting photons of certain frequencies as electrons move down energy levels

The absorption spectrum is caused by
