The types of transmission media include solids, liquids, gases and plasma; what all transmission media have in common is that they have the ability to propagate energy waves. Sound waves, for example, can pass through solids, liquids and air, and the effects of these different transmission media cause the sound to come through with various alterations.Continue Reading
One can consider how voices sound when they are across a room, on the other side of a wall or when the listener is underwater. Even when the original sound remains identical, the perception of the listener is going to be significantly different because of the effects that the specific transmission medium has on the sound waves.
When no material medium exists, the vacuum that exists often serves as a transmission medium for radio and light waves. These waves do not require a material substance to propagate, but when they do go through material transmission media, they undergo absorption, refraction or reflection, and the signal changes as a result.
Another definition for the term "transmission medium" refers to the actual device that puts the material medium to work for it. Examples include copper cables or optical fibers, and they facilitate the propagation of waves, whether electromagnetic, radio or sound.Learn more about Internet & Networking
Sound travels best through solids, followed by liquids and then gases. If there is not a state of matter for sound to travel through, there is no sound.Full Answer >
Although non-metals can be gases, liquids or solids at room temperature, most are gases. These include hydrogen, helium, neon, nitrogen, oxygen, fluorine, argon, chlorine, krypton and xenon.Full Answer >
Most solids, liquids and gases expand when they are heated because the molecules that make up the substance move more rapidly, which puts more distance between each of the molecules. This property of matter hold true irrespective of the state of matter in most cases. There are exceptions to this general rule; water, for example, expands when it transitions from liquid to solid form.Full Answer >
The five states of matter include Bose-Einstein condensates, solids, liquids, plasmas and gases. Matter is anything that occupies space and has weight. Matter may change its state when energy is increased or decreased.Full Answer >
