What is the means of transmission?
1 : an act or process of transmitting, spreading, or passing along the transmission of a disease. 2 : the gears that pass power from the engine to the axle that gives motion to a motor vehicle. transmission. noun. trans·mis·sion | \ tran(t)s-ˈmish-ən , tranz- \
What is an example of transmission?
An example of transmission is when something travels over cable wires to get to its destination. An example of the transmission of a virus is when a person spreads a cold virus by sneezing on someone else. The sending of a signal, picture, or other information from a transmitter.
What does transmission mean in microbiology?
The spreading of microbes is called transmission. Transmission involves the following stages: Escape from the host or reservoir of infection (where the infectious agent normally lives and multiplies). Transport to the new host. Entry to the new host.
What is transmitting in science?
transmission. 1. (Science: microbiology, physiology) A passage or transfer, as of a disease from one individual to another or of neutral impulses from one neuron to another. 2. ( Science: genetics) The communication of inheritable qualities from parent to offspring.
What is transmission of virus?
For transmission of a virus to occur, a virus must enter a host through a portal of entry, replicate or disseminate within the host, and be transmitted to a new host through a portal of exit.
What is transmission scientific waves?
The definition of the transmission of waves is the movement of a wave through a medium. For example, radio waves move information and energy from a transmission point to another location as the wave moves through the atmosphere.
What is absorption and transmission?
Reflection, transmission and scattering leave the frequency of the radiation unchanged. Exception: The Doppler Effect causes a change in frequency when the reflecting material or surface is in motion. Absorption is the transformation of radiant power to another type of energy, usually heat, by interaction with matter.
What is transmission biochemistry?
Chemically mediated transmission is the major means by which a signal is communicated from one nerve cell to another and is the mode of neuronal communication on which this and the next chapter focus.
What does transmission mean in waves?
When the electromagnetic waves arrive at the boundary between the two materials it gets reflected, absorbed or transmitted. When the electromagnetic waves pass through the material it is called transmission.
How does transmission occur?
More specifically, transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host. This sequence is sometimes called the chain of infection.
What is method of transmission?
A method of transmission is the movement or the transmission of pathogens from a reservoir to a susceptible host. Once a pathogen has exited the reservoir, it needs a mode of transmission to the host through a portal of entry. Transmission can be by direct or indirect contact or through airborne transmission.
How are bacteria transmitted?
Bacteria are transmitted to humans through air, water, food, or living vectors. The principal modes of transmission of bacterial infection are contact, airborne, droplet, vectors, and vehicular.
What is an example of transmission in waves?
For example, when shining white light into the fish tank, you see the color blue because blue light is being transmitted while all other colors are being absorbed. Similarly, when white light hits a leaf, all visible colors are absorbed except green, which is reflected onto your eyes.
Are absorption and transmission the same?
The main difference between absorbance and transmittance is that absorbance measures how much of an incident light is absorbed when it travels in a material while transmittance measures how much of the light is transmitted.
What is transmission in pharmacology?
In medicine, transmission is the passing of a disease from an infected individual or group to a previously uninfected individual or group.
What is chemical transmission?
Chemical transmission is the major means by which nerves communicate with one another in the nervous system. The pre- and postsynaptic events are highly regulated and subject to use-dependent changes that are the basis for plasticity and learning in the CNS.
What is an example of transmission in science?
Food and water contamination – Some diseases are passed on by contaminated food or water.
What is the definition of transmit in science?

The system transmits information over digital phone lines. 2 [ transitive] formal. if an object or substance transmits sound or light, it allows sound or light to travel
What is the scientific definition of transmission?
transmission. (trænzˈmɪʃən) n. 1. the act or process of transmitting. 2. something that is transmitted. 3. (General Physics) the extent to which a body or medium transmits light, sound, or some other form of energy.
What is transmission in science?
Transmission of light is the moving of electromagnetic waves (whether visible light, radio waves, ultraviolet, etc.) through a material. This transmission can be reduced, or stopped, when light is
