MASS DEFECT

Some images won't load. Is it just me or.. >_<

YEAH! Test 2 is easier tho. >_>

Week 7

Bless my paper. Oh well... on our chapter test -_- , I messed up in T1 which is multiple choice. X marks lined up. But I'm doing good in T2 which is solving. Soo yeaaah, remedial -_-''. I should've done better.

I feel like posting a meme about this after.

Week 6

LENS TERMINOLOGY

>> Optical center - the center of the lens

>> Principal axis - line joining the center of curvature and passes through the optical center

>> Secondary ray - ray passing through the optical center but not parallel to the principal axis

>> Focal length - the distance between the focus and the optical center

Week 5

DIVERGING AND CONVERGING LENSES YOOOHOOOO!!

Converging Lenses

As long as the object is outside of the focal point the image is real and inverted. When the object is inside the focal point the image becomes virtual and upright.

Diverging Lenses

The image is always virtual and is located between the object and the lens.

So what I've learned with this is that when the image is formed on the right side, the image is real. When the image is formed in the left side, the image is virtual. Completely opposite with mirrors. ;) Am I smart yet? Nehehehe

#lens #physics #converging #diverging

How is it going? ;)

Kinda blurry >_< so deal with it. It's quiet easy eh?

The example our teacher gave us. :D

Week 4

SNELL'S LAW AND INDEX OF REFRACTION

Snell's law states that the ratio of the sines of the angles of incidence and refraction is equivalent to the ratio of phase velocities in the two media, or equivalent to the reciprocal of the ratio of the indices of refraction

Index of Refraction is equal to the speed of light in vacuum over the velocity of light in the particular medium.

n=c/v

C= 3.0 x 10^8 m/s (speed of light in vacuum)

*Light travels slower in matter than in vacuum

So far I understand our topic. Adios amigos !!

Week 3

So... This week we discussed about the bending of light on concave mirror. At first I was confused on how to describe the image formed but later I've figured it out how . So yeah! Aha

Week 2

Unfortunately, we didn't have our classes this week. But, oh well. I'm looking forward to learn more about mirrors. Yay!

LAWS OF REFLECTION

1. For flat surfaces, it is found that: the incident ray and reflected rays lie in the same plane with the normal to the surface.

2. The angle of incidence equals the angle of reflection.

Definition of terms:

Regular reflection - when a reflection takes place in a smooth surface. Uniform reflection.

Diffused reflection - when a surface takes place on a rough surface.

Real image - image that can be projected on screen

Virtual image - image which appear to be like behind the mirror

Week 1

Hey ya there! This week, we tackled about Light Geometric Optics. It is an interesting topic tho. I think I've fully understand the concept of light. Light travels in a straight path and it behaves like a wave or particle.

So, LIGHT! Light forms an image. Yes it is (well of course). Without light, you wouldn't see anything and you'd be running into the walls, I guarantee it haha.

We also tackled about reflection and image formation by plane mirrors. So, in order to understand mirrors, we must understand light. It is quiet fun learning about mirrors. I used to hate physics before, but now I'm enjoying. I'm actually proud of myself because I understand our lesson.

I'll be posting my notes later :D
