Simulations

Questions:

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

Moving fast takes more energy.

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


3. Determine the frequency of the provided wave(frequency 27, amplitude 50)in Hz?
.98hz

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

3.7hz

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

.95hz

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

60cm

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

18cm

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


The frequency and wavelength are all co dependent upon the amount of energy put out, if energy is put out at a faster, and more powerful rate the frequency will increase, decreasing the wavelength. If energy is less and at a slower rate the frequency decreases and the wavelength increases.
