Reorder the following from HIGHEST energy to LOWEST

• 
• 
• 
• 
• 

The image shows the eV for electrons at each energy level for a particular atom

Which jump would require more energy?

n1--> n2

n3 --> n6

Justify your answer using MATH!

Which has the LONGEST wavelength and, therefore, the lowest frequency/energy

• Gamma Rays
• Radio Waves
• Visible Light
• Infrared rays

Which has the SHORTEST wavelength and, therefore, the highest frequency/most energy

• Radio waves
• Ultraviolet Rays
• Gamma Rays
• X-rays

Wave C and wave D are similar waves that are being compared. If the frequency in wave D doubles, how would the wavelength change?

• Wave D's wavelength would be cut by a fourth.
• Wave D's wavelength would be multiplied by a factor of four.
• Wave D's wavelength would be cut in half.
• Wave D's wavelength would be doubled.

Using the Bohr model of an electron orbit, which photon absorption will cause an electron transition from n=2 to n=3
