Ok...minggu depan kita akan masuk chapter yg seterusnya.. cgu dah berikan notes pun ( set 5 ). Cuma cgu nk share gambar2 nie.. supaya lebih  faham dan jelas.

1. How We See :

2. Bending Light :
The speed of light (about 3,000,000 meters per second!) is the speed light travels in a vacuum. (A vacuum is a space without atoms or molecules that cannot conduct heat or transmit sound waves.) When light has to travel through a material, such as water, it moves somewhat slower. Putting the brakes on the speed of light causes the light to bend as it passes from one medium (such as air) to another (such as water). This is called refraction. Refraction is what causes a spectrum to form, as different wavelengths of light bend at different angles. 

 


3. Reflecting Light :


Reflection is most likely the property of light that we experience most often. Looking at yourself in a mirror, seeing the reflection of the sun in the ocean at sunset, and the sight of a mirage on the hot desert sand are all examples of reflection. 

4. Light waves and the rules of reflection

To see an object light has to reflect off the object. Light reflects of all objects and looks different due to how the light reflects of it.
light reflects of rough surfaces differently depending if the surface is rough or smooth.

Light hits a mirror and bounces off it. This process is called reflection. A incident ray is a ray that of light that hits an object, in this case a mirror. A ray of light that bounces off the mirror is called the reflected ray. There are three rules of reflection: 

Rule 1: The angle of incidence ray is always the same size as the angle of reflection. (0i = 0r)

Rule 2: The image is always the same distance behind the mirror as the object is in front.
Rule 3: The image is always;
- The same size as the object.
- Laterally inverted (left becomes right and right becomes left), which is why writing is back to front in a mirror.

 Ok...That's all..sehingga jumpa lagi...!! Salam sayang dari cgu..!!
