Week 5: June 30 - July 4 (2k14)

Last week's physics lesson was all about index of refraction and how light reflects and refracts in a converging and diverging lens.

In a diverging lens, light scatters when it passes. In a converging lens, the first ray of light passes through the F prime. The second ray, passes through the optical center and the last ray passes through the F.

Ci dev'essere una spiegazione migliore del modello standard e più comprensibile delle Stringhe. La supersimmetria mi ispira ma non è ancora sufficientemente immediata. Dev'essere una di quelle cose che quando le capisci ti batti una mano sulla fronte esclamando «Ovvio!» e domandandoti come potessi non averla vista prima

Then you'll see, that it is not the spoon that bends, it is only yourself. #thematrix #theone #advancedphysics

Week 4: June 23-27 (2k14)

This week, our teacher tackled about Index of Refraction, Snell's Law, Concave Mirrors and Lenses.

We have recalled that the speed of light is approximately equal to 3.0x10^8 m/s. So, when light passes from low optical density to higher optical density, the speed of light decreases. Therefore I conclude that the speed of light differs in medium and optical density.

I have also learned that:

The index of refraction is equal to the speed of light in vacuum divided by the speed of light in medium. n=c/v.

The Snell's Law which was formulated by Willebrord Snell (1621), states that---Law of Refraction: The incident and refracted rays lie in the same plane.

The wavelength of light changes as it passes to one medium to another.

Diverging lenses are lenses that has a thick surface at the edge and thin surface at the center. Converging lenses are the opposite of these.

There are types of converging lens: double convex, plano convex, and convex meniscus.

There are types of diverging lens: double concave, plano concave, and concave meniscus.

Week 3: June 16-20 (2k14)

I like our classes this week in Physics because I've already understood how the bending of light in a concave mirror works.

Last wednesday or I think friday, we were checking our papers about the quiz we've answered last 2 weeks ago.  I got a low score and I wanted to retake that quiz again because I've already understood that particular lesson. But too bad, it did not happen anyway.

After our checking, our teacher proceeded to another topic. That topic includes some equations and again, I did not understand it. Our teacher again, gave us an exercise about what he discussed earlier. And again, I got the wrong answer and I only understood the topic AFTER the discussion, the quiz----everything. 

I hope next time things will become easier for me. I don't want this situation to happen again. :(

Week 36-37: February 16-27

In these weeks we just reviewed our lessons in Physics for the upcoming National Achievement Test.

[drozymesxza-blog]

Week 31: January 12-16 (2k15)

So on January 13 our lesson in Physics was all about  Circuit Protector, fuse, and circuit breaker.

Circuit Protector- to protect circuitry at home (Accidents at home are caused by “faulty wiring.”)

Fuse- protects the circuit by stopping the whole circuitry through melting.

Week 24-29: November 10- December 19 (2k14)

When I reviewed my notebook in Physics, I had not seen any notes on these dates. Maybe this was the time when the coaches and contestants were preparing for the Science Quest.

Week 22: October 27-29 (2k14)

On October 27, we dealt with the topic Electromagnetism. Electromagnetism was coined from the word “electricity” and “magnetism.”  The word electricity also comes from the greek word “elektron” which mean “amber.”

 The two types of charges (According to Benjamin Franklin):

         1. positive

         2. negative

Note: Unlike charges attract, like charges repel.

Law of Conservation of electric charge.

The net amount of electric charge produced in any process is zero.

Coulomb’s Law

Charles Coulomb (1736-1806) investigated electric forces in the 1780s using a torsion balance much like used by Cavendish for his studies of the gravitational force

Fe=kQ1Q2/r^2

---

The discussion of Coulomb’s Law was then continued on October 29. In Coulomb’s Law, electric force increases if unlike charges are near.

In the equation F=Keq1q2/r^2, Ke is equal to 9x10^9 N.m^2/c^2 or ke= 1/4πE0 where E0=8.85x10^-12.

Charging means gaining or losing electrons.

Charging can be through:

            -Friction/Rubbing:

             Net charge= 0 = conserved

            -Induction

            -Conduction

Week 20-21: October 13-24 (2k14)

We had no classes on October 13-17 due to busy schedule and also on October 20-24 because it was our semestral break.

Week 15-19: September 8 - October 10 (2k14)

Since I don't have new notes and I ran out of leaves in my notebook... If my memory fails me not, we only had some exercises this week about mass defect, binding energy and computing the mass defect of nuclear fission which we can get it from this equation: △m=Mreactants - Mproducts.

Week 14: September 1-5 (2k14)

In this week, we talked about Radiation Applications. First we can apply radiation to food and agriculture. Example when exporting goods, killing microorganisms and sterilizing male insects. Second, in diagnosis and therapy. For example, radioisotopic tracing can trace cancerous cells. Chemotherapy can somewhat help cure cancer. RIA Technique can be applied to hepatitis A virus.

Third, in radioactive dating. For example, in carbon-dating, we can use isotope carbon 14 to identify age of living organisms. Another example is uranium-dating. Uranium 238 and 235, Thorium and Potassium can help identify the age of non-living things.

Another topic we discussed this week is mass defect and binding energy.

To find mass defect, you need to subtract atomic mass from the nuclear mass. To do this. first, you need to find the mass of the element's protons and neutrons. Here's the constant value:

Mp+= 1.0073 amu Mn =  1.0087 amu

For instance you're finding the mass defect of Lithium which has an atomic mass of 6.9380 and atomic number 3. So... Mp+= 1.0073 amu * 3 = 3.0919 amu Mn = 1.0087 amu * 3 = 3.0961 amu

Adding both products will result to nuclear mass. So the nuclear mass is 6.9380 amu.

Now start subtracting...(△m= mass defect) △m = nuclear mass-atomic mass △m = 6.9380 amu - 6.0480 amu △m = 0.8900 amu

Now to find the binding energy, here's the formula: BE= △mc^2 BE of lithium=( 0.8900 amu ) (931 MeV/amu) [Here, we need to convert amu to MeV (Mega Electrovolts)]

So the answer is:

BE= 828.59 MeV

Week 13: August 25-29 (2k14)

We talked about Radioactive Decay this week.

84 or more protons are radioactive.

Transmutations - radioactive decay.

Half-Life = original amount/2^n

(We only had our class on Aug. 26)

Week 12: August 18-22 (2k14)

I think we didn't have our class this week because I didn't have notes.
