​How to complete this activity

​Use the play button to hear me explain the concepts and what you need to take away. My suggestion would be to go through and take the notes, then go back and listen so that you can understand for the next assignment.

Poll

Where do you feel you are on the scale?

• I already know all of this.

• I know about the spectrum but not Bohr.

• I know some of the spectrum.

• What is the electromagnetic spectrum?

Multiple Choice

Multiple Choice

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

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

Multiple Choice

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