When radio waves hit the Earth's atmosphere, they can be absorbed, reflected, or refracted. Some radio waves may continue through the atmosphere and reach the Earth's surface, where they can be picked up by antennas and receivers for communication or broadcasting purposes. The Earth's atmosphere allows radio waves to travel long distances without much degradation, making them valuable for long-range communication.

What happens when s waves hit the outer core of earth?
S-waves cannot travel through the liquid outer core because it cannot support shear stress. Instead, they are either absorbed or reflected when they reach the outer core boundary, causing a shadow zone on the opposite side of the Earth from the earthquake where these waves are not detected.
How do seismic waves behave when they encounter a fault?
Seismic waves can be reflected, refracted, or diffracted when they encounter a fault. The behavior of the waves depends on the orientation and properties of the fault. Additionally, seismic waves can generate new waves when they interact with a fault, contributing to complex wave patterns in the Earth's subsurface.
How do people now about earth layers?
From earthquake waves. There are 2 types of waves, p or primary waves and s or secondary waves that are generated when an earthquake occurs. Both types of waves move away from the epicenter of the earthquake in all directions including "down" through the layers of the Earth under the epicenter. Both waves start out at the same time from the same spot, but P waves move through the earth faster, hence the name primary waves. The farther the earthquake monitoring equipment is from the epicenter the bigger the lag time between when the p and s waves arrive. Monitoring stations on the side of the Earth opposite the epicenter do not receive any S waves. This is because S waves only move through solids so when the S waves hit the liquid outer core, the energy from these waves dissipates. When you move out far enough perpendicularly from the epicenter, S waves show up again on monitors. By overlapping these "shadow zones" from multiple quakes around the world, the depth at which the liquid outer core begins can be determined.
What happens after the suns rays hit the earth?
After the sun's rays hit the Earth, the energy is absorbed by the land, water, and atmosphere. This energy is converted into heat, which warms the Earth's surface and drives the planet's weather patterns and climate.
How do earthquakes transmit energy?
The energy of the quake is transmitted through the ground. It's that simple. There are a couple of different waves that move through the earth, and you know them as the longitudinal and transverse waves, the so-called seismic P-waves and S-waves, respectively. A parting idea might be that an earthquake is the release of (seismic) mechanical energy, and, as with all mechanical enery, that energy is transferred into and is carried by the wave. You'll find a link below.The velocity of seismic waves is dependent on the density and stiffness of the the material (more specifically the bulk and shear modulus). P wave velocities are typically in the range of 6-8 km/s and S-wave velocity is typically around 60% of that of the P-wave.
How do different obstacles affect radio waves?
Radio waves hit all obstacles the same, but the waves will differ in the distance of the wave and/or the object from the transmitter.
Do radio waves hit the ionosphere?
Yes. The result is that some fraction of the radio energy, depending on its frequency and ranging from none of it to all of it, is bent back down to Earth. The rest continues on through the ionosphere into space.
What happens when an earthquake occurs far from an observing station?
P-waves hit, followed by S-waves, followed by surface waves.
What causes the fluttering of radio reception when an airplane flies overhead?
okay fluttering is due to reflection/interfearence of sound waves between an aeroplane and the radio.therefore this is what happens when the radio station send the radio waves directly a radio receive the waves but fluttering occurs when an aeroplane interfearring the path of transmission where by some of the waves form radio station will hit an aeroplane and goes to a radio and also part of the wave will go direct to a radio therefore simultaneously receiving of radio form two different places is what causes fluttering!
What is electromoagnetic waves?
Electromagnetic waves refer to a whole family of waves that are emitted by moving charges. These include gamma rays, xrays, ultraviolet light, regular light, infrared light, microwaves and radio waves. They all have the same basic characteristics but have dififferent frequency and wavelength ranges. They are made up of electric and magnetic fields. These fields can exert forces on charges they hit and cause them to move. So radio waves emitted by a radio station transmitter travel thru space and hit the antenna in your radio. This causes the charges in the antenna to move which is then converted back into sound. Light waves that hit your arm cause the charges to move and you feel warm etc.
What happens when electromagnetic waves hit an object?
When electromagnetic waves hit an object, they can be absorbed, transmitted, reflected, or scattered. The interaction between the waves and the object will depend on the material properties of the object and the frequency of the electromagnetic waves.
What happens when waves hit the shoreline?
When waves hit the shoreline, they slow down and their energy is transferred to the coast. This can cause erosion of the shoreline, as the waves carry sediment away. The waves can also break, creating turbulence and causing sediment to be deposited on the beach.
How is it salt water burns when hit with radio waves?
It seems all the scientists are at a loss....what a pityfull pride-dicament.
When you Trace the energy transformations from radio signal to the music you hear?
When a radio signal is received by the radio, it converts the electromagnetic waves into electrical signals that get amplified and converted into sound waves by the speakers. The sound waves then travel through the air and hit your eardrums, causing vibrations that are converted into electrical signals in your brain, allowing you to perceive the music.
What happens to seismic waves when they hit the MOHO?
When seismic waves hit the Moho (Mohorovičić discontinuity), they can either be reflected back to the surface, refracted as they pass through the boundary, or converted into a different type of wave. This boundary separates the Earth's crust from the underlying mantle, resulting in changes in seismic wave behavior.
Are radio waves made up of matter?
Radio waves are electromagnetic waves, which consists of electric & magnetic fields. When they hit matter they exert forces on the charges of the atoms that make up the matter. Radio waves are usually pretty weak so when they hit most materials not much happens because the atomic charges are pretty firmly in place. However, in metals some of the atomic electrons are not firmly in place and will be easily moved by a radio wave. This is why antennas work. The radio wave causes currents in the antenna which can be sent to a circuit which can convert the currents into the information that was sent by the radio wave (TV & Radio), if it was carrying information.
Which type of radiation from the sun is the longest wavelength?
Radio waves are at the long wavelength end of the sun's emissions.
