Radio waves are a type of electromagnetic radiation that are emitted by accelerating electric charges. When electrons within an antenna are oscillated or accelerated, they create electromagnetic waves at radio frequencies. These waves then propagate through space and can be received by devices like radios or antennas.
Waves are formed by wind blowing across the surface of the water, creating ripples that develop into waves. When waves approach the shore, they interact with the coastline, shaping it through erosion and deposition. Stronger waves can erode cliffs and create sea caves, while deposition of sediment from waves can form beaches and sandbars.
Wave cut platforms are formed through the erosional action of waves on a rocky coastline. As waves pound against the rock over time, they wear it down and create a flat and level surface. This process is aided by factors such as the presence of softer rock and the abrasion from sediment and debris carried by the waves.
In the Earth's outer core, which is composed of molten iron and nickel, seismic waves (P and S waves) are not able to travel through it due to its liquid state. This causes a shadow zone on the opposite side of the Earth from a seismic event, where P waves are completely deflected and S waves are not detected.
there are 3 types of shock waves produced by an earthquake:the P waves which is known as the (primary or compression) waves are the first to arrive at the recording station, p waves are formed when matter in the rocks is pushed together by the earth's movement. they can travel through solids and liquids.the S waves which is known as the (secondary )waves are the second waves to arrive at the recording station. this waves are also called the shear waves. these waves are formed by the sideways motion of matter, it can only travel through solids.BSecondary waves are also known as shear waves and primary waves are also known as pressure waves.
When waves cut completely through a headland, a feature called a sea cave is formed. Sea caves are formed by the relentless erosion of waves gradually wearing away the weaker rock layers of a headland. Over time, the waves create openings and cavities that can extend deep into the headland.

Light waves are formed through the vibration of electric and magnetic fields, creating electromagnetic radiation. This radiation travels in waves, moving in a straight line until it interacts with something, such as matter or other waves. The frequency and wavelength of these waves determine their characteristics, such as color and energy.
The shadow zone is formed due to the bending of seismic waves as they pass through the Earth's outer core, which is made of liquid iron. P-waves slow down and refract in the outer core, causing a gap in their detection on the opposite side of the Earth. S-waves do not travel through the liquid outer core and are completely blocked, creating a secondary shadow zone.
Radio waves are a type of electromagnetic radiation that are emitted by accelerating electric charges. When electrons within an antenna are oscillated or accelerated, they create electromagnetic waves at radio frequencies. These waves then propagate through space and can be received by devices like radios or antennas.
S-waves, or secondary waves, cannot travel through water because they oscillate perpendicular to the direction of wave propagation. Water lacks the necessary material properties (shear strength) to transmit these waves.
A surf is formed when the waves get to high and cause waves to "break."
Three waves can move through various materials, including solids, liquids, and gases. In solids, such as metals and rocks, the waves travel through the particles by causing vibrations. In liquids, like water and oil, the waves propagate by disturbing the fluid molecules. In gases, such as air, the waves create pressure variations as they travel through the medium.
A sea arch is formed by the erosive action of waves crashing against a headland or cliff, gradually wearing away the rock through processes like hydraulic action and abrasion. Over time, a small hole is formed, which enlarges and eventually erodes through the headland, creating a natural arch. Continued erosion may cause the arch to collapse, leading to the formation of a sea stack.
Waves are formed by wind blowing across the surface of the water, creating ripples that develop into waves. When waves approach the shore, they interact with the coastline, shaping it through erosion and deposition. Stronger waves can erode cliffs and create sea caves, while deposition of sediment from waves can form beaches and sandbars.
The waves from an earthquake that travel through the Earth's interior are known as body waves. There are two types of body waves: P-waves (primary waves) and S-waves (secondary waves). These waves contribute to the shaking and damage caused by an earthquake.
Surface waves are formed when the waves reach the Earth's surface. These waves travel along the boundary between the Earth and the atmosphere, and they can cause both lateral and vertical movements of the ground.
