Blog Post 5: Wave interference Sims

1. Measure the wavelength of two drops of different amplitude, leave frequency constant. Drop 1 is 1.73cm and Drop 2 is 1.67cm

2. Measure the wavelength of two drops with different frequency, leave amplitude constant. Drop 1 is 4.45cm and Drop 2 is 1.07 cm

When you change the amplitude of a wave you do not change the energy therefore your wavelength should be exactly the same. any differences are due to human error in the measuring process.

When you change the frequency of a wave you are changing its wavelength because frequency and wavelength are directly related.

4. Introduce a second faucet for the next set of questions.
- measure the wavelength of the two drips, in cm
- then measure distances from each drip(red dots) to the 6 constructive interference points (yellow dots) and report these values, cm
the wavelength of the drops of water were both 1.2 cm.
distance from faucet one then two respectivly 
A=3.08 cm,4.54 cm
B=3.06 cm, 2.99 cm
C=4.57 cm, 2.97cm
D=4.62 cm, 6.32 cm
E=4.7 cm, 4.47cm
F=6.18 cm, 4.41 cm

Blog Post 3: Simulations

the faster the speed the more calories are burned.
higher frequencies relate to higher energy.
when frequency is 27 than .98 hertz
when frequency is 100 than 3.7 hertz
when amplitude is 100 and frequency is 27 than it is still .98 hertz
the wavelength of frequency 27 is approximatly 60 cm
the wavelength of frequency 100 is approximatly 16 cm
the more energy something has the shorter its wavelength, which means it has a higher frequency.

Blog post 2: Unit cell of NaCl

Unit Cell of NaCl
the height, width, and lenght of one unit cell of NaCl is approximatly .464 nm, 46.4 angstroms, 4.64x10^-10m.
the mass of one cube of salt is approximatly 5.85x10^-5 grams, and every cube is approximatly 1.01x10^-11 moles
the dimensions of a single cube of NaCl is approximatly .161mX.161mX.161m, and there are a total of  NaCls in one cube of Salt.

Blog Post 1: atoms and moles galore

Describe 10 nm: If a beachball were equzilant to 2 nm than we would have to travel 1 light year to equal one meter.

Compare mole to an atom. If an atom were equvilant to 1ml of water than we would need two indian oceans worth of water to get an equvilant mole.
