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 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.
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.
How do you calculate eot crane lt wheel?
how i will calculate eot crane long travel 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.
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.
Medium waves travel faster at night because.?

Can for ultrasound wave travel long distance in air?
No, ultrasound waves cannot travel long distances in air due to the high attenuation of the waves caused by air. The waves lose energy quickly as they travel through air, limiting the distance they can travel effectively. Additionally, scattering and absorption of ultrasound waves in air further reduce their ability to propagate 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.
Does energy travel through water?
Yes, energy can travel through water in the form of waves, such as sound waves or electromagnetic waves. These waves can propagate through water and carry energy over long distances.
Waves that travel at the surface such as Raleigh and long waves?
Raleigh waves are surface waves that occur in many types of media, such as water and the Earth's crust. They cause the ground to roll up and down in a wave-like motion during an earthquake. Long waves, or long-period ocean waves, are also surface waves that have longer wavelengths and occur in the ocean due to forces such as gravity and wind.
What type of waves can be transmitted in a vacuum?
Electromagnetic waves, such as light waves and radio waves, can be transmitted in a vacuum because they do not require a medium to travel through. These waves propagate through the vacuum of space and can travel long distances without the need for a medium.
How long would it take sound waves to reach Pluto?
Sound waves can't travel through space.
What is a distinctive characteristic of radio waves?
One distinctive characteristic of radio waves is their long wavelength compared to other types of electromagnetic waves. This allows radio waves to travel long distances and penetrate obstacles like buildings and clouds.
In what ways are sound waves and electromagnetic waves different?
Sound waves require a medium to travel through, while electromagnetic waves can travel through a vacuum. Sound waves are mechanical waves that require particles to propagate, while electromagnetic waves are made up of oscillating electric and magnetic fields. Sound waves are slower than electromagnetic waves and are typically used for communication over short distances, while electromagnetic waves can travel long distances at the speed of light.
Why is it safe to travel into the wind and on the ocean waves?
It is safe as long as there is someone experienced.
