Questions:

1. which takes more energy, slow up and down, or fast up and down?

2. fast frequency corresponds to low energy or high energy?

3. Determine the frequency of the provided wave(frequency 27, amplitude 50)in Hz?

4. Determine the frequency of the provided wave(frequency 100, amplitude 50) in Hz?

5. Determine the frequency of the provided wave(frequency 27and amplitude 100) in Hz.

6. What is the wavelength of the provided wave(frequency 27, amplitude 50)in cm?

7. What is the wavelength of the provided wave(frequency 100, amplitude 50)in cm?

8. Describe the relationships between energy, frequency and wavelength. Include descriptions for relationships of all three.
