Blog 3: Waves

1. The fast up and down movement to create the waves takes more energy. 
2. Fast frequency corresponds to high energy because the fast up and down movement used more energy.  Frequency is equal to one divided by the period.  With the fast up and down movement, or high energy, there are more periods of the wave being created. 
3. Having the frequency set at 27 with the amplitude set at 50 it took 1.02 seconds to go through one cycle, so it ends up being 0.98 Hz. 
4. Having the frequency set at 100 with the amplitude set at 50 it took 0.27 seconds to go through one cycle, so it ends up being 3.7 Hz. 
5. Having the frequency set at 27 with the amplitude set at 50 it took 1.02 seconds to go through one cycle, so it ends up being 0.98 Hz.
6. When the frequency is set to 27 with the amplitude set at 50 the wavelength, trough to trough, shows 20 cm to 81.5 cm.  This being said the wavelength is equal to 61.5 cm.
7. When the frequency is set to 100 with the amplitude set at 50 the wavelength, trough to trough, shows 10 cm to 26.5 cm.  This being said the wavelength is equal to 16.5 cm.
8. Energy is proportional to the frequency because the higher the energy, the higher the frequency.  Energy does seem to affect the wavelength..  With the waves that had a higher energy the wavelength was smaller.  With this higher amount of energy there became more waves that were closer together.  The wavelength is also affected by the frequency though.  In other words, energy and wavelength have an inverse relationship.  The wavelength is equal to the frequency multipled by the velocity; in other words the frequency and how fast the waves are moving; the faster the waves are moving the more energy there is.

blog post 1: describe 10 nm and mole of atoms

The size of 10nm is equivalent to the thickness of a cell wall and the diameter of a virus cell.  The diameter of an insulin molecule is actually 5nm, so two of those could be equivalent to it as well.  In other words, the size of 10nm is extremely small.

A mole on the other hand, is the complete opposite.  Imagine the amount of ocean water there is on planet Earth.  That number amount is actually 3.586 * 10^20 gallons of water.  A mole is equal to 6.02 * 10^23.  If we took the Earth and multiplied it by 100, the amount of water we would have would be ALMOST equal to a mole.  In fact it would still slightly be smaller than a mole of atoms.  In other words, the size of a mole of atoms is extremely large.
