Just a straight line, but when the light exposure to a substance occurs when the refraction and reflection. We often see the glass and mirrors, "reflective" refers to the reflection of light; half of the straight stick into the cup is no longer a straight look is an illusion caused by light refraction. In fact, we have been able to see a variety of objects, that are caused by refraction and reflection of light (if there is no light, we could not see anything.)Propagation of light in a vacuum can also be spread in certain substances, certain substances mentioned here, is called in the optical media or medium terms. Glass, quartz, air, water, clear plastic so the light can be transmitted, they are the medium of light transmission. Different medium density is not the same, such as we know the density of water is much larger than the air. Seemingly similar substances (such as glass and quartz), and their density is not the same. So, is divided into "light denser medium" and "light sparse media." When the light from one medium will be injected into another medium refraction, like turning the light child friends. Even with the same material, also produced by some of the density of different environmental conditions, such as the air somewhere hot (low density), somewhere in the cold air (high density), the light passing through hot and cold air can also occur when t...
