Medium waves travel faster at night because.?
Because in day time the ionisation is less in the D layer of the Sky. So it absorbs the medium waves because of its lower frequencies. In night time the D layer vanishes and the Medium waves travel towards the F layer and reflected back to the earth from a long distance. That's why Medium waves are clearly heard in night times from a long distance.
What are the dangers of radar waves?
X ray waves are harmful if exposed frequently or for a long time because they penetrate into our body, in the process they cause damage to the cells in the body. This effect can also cause cancer.
What is the difference between a capillary tube and a expansion valve?
The throttling devise can be the valve or the copper tubing that allows the flow of the refrigerant through very small opening also called as the orifice. The throttling devices allow restricted flow of the refrigerant. The throttling devices are also called as the expansion valves because when the refrigerant passes through them the pressure of the refrigerant drops down or it expands..Capillary tube is one of the most commonly used throttling devices in the refrigeration and the air conditioning systems. The capillary tube is a copper tube of very small internal diameter. It is of very long length and it is coiled to several turns so that it would occupy less space. The internal diameter of the capillary tube used for the refrigeration and air conditioning applications varies from 0.5 to 2.28 mm (0.020 to 0.09 inches). Capillary tube used as the throttling device in the domestic refrigerators, deep freezers, water coolers and air conditioners.
How do you calculate eot crane lt wheel?

Why do you need or use robots?
Robots are faster and easier than us humans working, plus in the long run cheaper...do not have to pay salary.
Electromagnetic waves travel faster over land or water?
as long as they are both traveling through the air, then the speed is the same.
Waves that travel at the surface such as Raleigh and long waves?
surface waves, raleigh waves, and long waves.
Does sound waves travel faster in water and liquids?
I assume you mean: Does sound waves travels faster in water opposed to air. Yes, yes it does, because sound waves travels by pushing a molecule into another molecule and so forth. The difference between water and air is simply, that the molecules are closer in water, in that way the molecule doesn't have to travel so long before passing on the momentum. That's why the sound can travel both faster and longer in water, whales among others benefit from this, as it enables them to communicate over long distances.

What waves transfer from one place to another?
All waves can travel from one place to another as long as they have a medium to travel through. The only waves that do not need a medium are electromagnetic waves. When using the word "transfer" though. Waves transfer energy; waves themselves are not transfered they simply travel.
Do radars have long or short waves?
Radar dectectors have very long waves. In fact they are longer than light waves which must travel all the way here from the sun.
How long would it take sound waves to reach Pluto?
Sound waves can't travel through space.
What can a siesmic wave do if it can travel through liquids gases and solids in the continental and or oceanic crust?
First we must define seismic waves, it consists in two forms, P-waves (longitudinal/compressional waves) and S-waves (traverse or shear waves), P-waves travel faster than S-waves and can pass through solids and liquids of the Earth's inner parts, however, they do least damage due to the way they move (up/down). S-waves, however, do the most damage, they move sideways and has a large amplitude and thus does the main damages earthquakes; nevertheless they do not travel through liquids. Therefore, seismic waves that travel through the Earth's crust does no damage as even close to the surface, the P-waves are virtually safe, travelling a long way, it runs out of energy.
Why is it safe to travel into the wind and on the ocean waves?
It is safe as long as there is someone experienced.
Do particles of water in ocean waves travel long distances to get to shore?
of course
Why does a trumpet have a her pitch than a tubaig?
the long distanec the sound waves have to travel before they get out
How long does it take sound waves to travel down your ear to your brain?
