Electromagnetic Spectrum

WOAH DOUBLE RAINBOW !!What does it mean ?!?!

HOW WE GONNA PLAY ??

This will help test how fast/accurate your knowledge about the electromagnetic spectrum is !

1. All questions are about waves and the electromagnetic spectrum (most of them are ranking)

2. Collaborate with your groups

3. Write your final answers on your dry erase boards

4. Questions will be timed (roughly)

5. Every right answer gets you a point

6. Most points win candy !!

Afterwards we will look at some mnemonics n’ things to remember the electromagnetic spectrum !!

FILL IN THE BLANK

1. Wavelength ( λ ) and Frequency (ν ) are _________related

2. Frequency (ν ) and Energy are ___________ related

3. Energy and Wavelength ( λ ) ___________ related

If I want to change the wavelength of this wave what color arrow do I manipulate?

Which of these waves has the most energy, which has the highest frequency?

This wave represents the lights in my room, I want to make my room darker, which property of waves should I manipulate? (e.g. frequency, wavelength, amplitude)Which color line represents this property?
