The refrective media of eye is composed of four parts of eye, the cornea which is the anterior 1/6 of the external tunic (fibrous tunic) of the eyeball. The aqueous humoris second part of the refractive media of eye, it is a colorless, transparent and watery fluid, it fills the chambers of the eye and is formed by active transport and diffusion from the capillaries of the ciliary processs from which it enters the posterior chamber then it passes into the anterior chamber throuh pupil and escapes from the iridocorneal angle into the sinus vinus sclerae through the space of iridocorneal angle, and finally drains in the opthalamic veins via anterior ciliary veins. The third part of the refractive media of the eyeball is the lens which is a adjustable, transparent and elastic, convex body lacking blood vessels and nerves and the convexity of its anterior surfac is less than the of it's posterior surface. The last one of the refractive media of eye is the vitreous body. The vitreous body is a colorless, transparent and jelly-like body which is fills the posterior fourth-fifths of the eyeball . It is also a condensed superficially to form a transparent envelope, the vitreous membrane. The refractive media is an important theory that you must understand in your anatomy courses especialy when you want to be an opthomologistbecause most cases of the eye come from the refractive media. In the conclusion the four refractive media of eye are the ones that were mentioned above that are : Cornea + Aqueous humor + Lens + Vitreous body Prepared by: Dr. Mohamed Esse Rage & Dr. Abdirahman Abdulkadir Issak, Wuhan Medical University, China

A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
It speeds up. Air and water are both media (plural form of medium). Each one of them has a different speed of light. As the incident ray passes from air to water, it refracts to be closer to the normal. A refraction occurs when there is a change in the speed of light. A change in the speed of light occurs when there is a change in media. In this case the media is changed from air to water. The second medium (water) must also have a lower speed of light in order for refraction to occur
Going from short wavelength light to long wavelength light, the order goes Red - Orange - Yellow - Green - Blue - Indigo - Violet (ROYGBIV)
Because it depend upon light
Yes all media can be sterilized at the same temperature in order to insure that all pathogens have been killed and that only the one from a cultured sample will grow.
media texts are created in order to: achieve the purposes of media producers

Media is a business because in order to print or show media, advertisement is sold. This means that money must exchange hands in order to keep media up and running, making it a business.
media is used in order to select and differentiate microorganisms
A proppant in an oilfield is a refractory element used in binding the leakages of oil wells in order to increase the productivity of an oil well.
Media messages are created by people using different tools.
suck a dick, you pricks
Ask yourself questions about what you see and hear around you
(Apex) Media are connected to networks that make information easier to share and access.
To achieve their goals, producers of media texts use tools such as cameras, editing software, sound equipment, lighting, and graphics design programs. These tools help them create engaging and impactful content that resonates with their target audience.
Media Bias.
A double rainbow is not unusual but is often too faint to be noticed. A rainbow is caused by sunlight refracting and reflecting in water droplets. If the light is reflected twice in the droplets, there will be a second rainbow outside the first. It will be fainter and the order of the colors will be reversed. Whenever you see a rainbow, look carefully to see if there is a second one right above it.
