Transcript of lights and optics
objects can be seen by the light they emit,or by the light they reflect . Reflected light obeys the law of reflection,that the angle of reflection equals the angle of incidence.
PROPERTIES OF LIGHT
Ray Model of light
The ray model of light consists of things that produce light
It also consists of many factors that alter the light like:
-Convex lenses and mirrors
-Concave lenses and mirrors
Law of Refraction
When a wave passes from one medium to another medium, the wave will change its direction.
the production of light by means of a chemical reaction in an organism
light emitted by a substance that has absorbed energy from another source
Vision requires many things. One of them being light as well as a cpu.
It is the process of transforming chemical energy into light energy with little or no change in temperature.
The radiation chemicals that doesn't require as much energy to power. Therefor is more efficient than an incandescent source. Today it is becoming a more popular and eco-friendly way to light our homes
Probably the most common way to energize atoms is with heat, and this is the basis of incandescence. If you heat up a horseshoe with a blowtorch, it will eventually get red-hot, and if you indulge your inner pyromaniac and heat it even more, it gets white hot.
Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has a wavelength in the range of about 380 nanometres (nm), or 380×10−9 m, to about 740 nanometres – between the invisible infrared, with longer wavelengths and the invisible ultraviolet, with shorter wavelengths
Thanks for watching

constructive criticism is encouraged but not if your gonna be mean about it.
Far sight: Vision is blurry when looking at far away images
Near Sighted: vision is blurry when looking at objects near the eye
