Blog Post 3: Waves

Question 1: Which takes more energy, slow up and down, or fast up and down?
Fast up and down will contain more energy

Question 2: Fast frequency corresponds to low energy or high energy?
A higher energy because it needs more energy to create the motion.

Question 3: Determine the frequency of the provided wave (27,50) in Hz
.98039 Hz

Question 4: Determine the frequency of the provided wave (100,50) in Hz
3.7037 Hz

Question 5: Determine the frequency of the provided wave (27,100) in Hz
.98039 Hz

Question 6: What is the wavelength of the wave (27,50) in cm?
58cm

Question 7: What is the wavelength of the wave (100,50) in cm?
16cm

Question 8: Describe the relationships between energy, frequency and wavelength.  Include descriptions for relationships of all three.
More energy increases frequency and decreases wavelength.
A higher frequency needs more energy and will decrease the wavelength.
A long wavelength means less frequency or less energy.

Height of Unit Cell - 1.104 nm, 11.04 angstroms, 1.104*10^-9

Length of Unit Cell - 1.104 nm, 11.04 angstroms, 1.104*10^-9

Width of Unit Cell - 1.104 nm, 11.04 angstroms, 1.104*10^-9

Mass of Unit Cell - 58.44277^3 or 199614.6335 atomic mass

Blog Post 1: describe 10 nm and a mole of atoms

10 nm = 1 * 10^-8 meters, or 0.00000001 meters
10 decimeters in a meter, 10 centimeters in a decimeter, 10 millimeters in a centimeter, 1000 micrometers in a millimeter, 1000 nano meters in a micrometer.

In other words, incredibly small.

A mole of atoms isn't exactly a standardized measurement system, depending on the substance a mole changes. H2O, for example, has a atomic mass of around 18.  In terms of a mole, you would need 18 grams of water to obtain a mole of water.
Gold (Au), on the other hand, has an atomic weight of 107.87.  To obtain a mole of gold you would need 107.87 grams of gold.

So the size and weight of a mole depends on what the substance is made of.
