When a seismic wave encounters a boundary, such as the interface between different geological layers, it can be reflected back, a phenomenon known as reflection. This occurs when the wave's speed changes due to differences in material properties, like density and elasticity. The angle of incidence, which is the angle at which the wave strikes the boundary, determines the angle of reflection, following the law of reflection. This bouncing back of waves is crucial for seismic imaging and understanding subsurface structures.
When a seismic wave bounces backward, it is referred to as reflection. This occurs when the wave encounters a boundary between different materials, causing part of the wave to return to the surface. This phenomenon is commonly used in seismic studies to analyze the Earth's subsurface structures.
refraction
When a seismic wave crosses a boundary between different materials, the process is called "refraction." This occurs because the wave changes speed as it enters the new medium, leading to a change in its direction. Additionally, if the wave is partially reflected back at the boundary, this is known as "reflection." Both processes are essential in understanding seismic activity and are utilized in methods like seismic imaging and exploration.
When a seismic wave encounters a boundary between two different materials, part of the wave may be reflected back, which is known as reflection. This occurs because the wave's speed changes due to the differing properties of the materials, such as density and elasticity. The angle of incidence equals the angle of reflection, similar to light waves. This reflection can provide valuable information about the Earth's internal structure when analyzed by seismologists.
He noticed that seismic waves changed velocity at measurable depths. The boundary where seismic waves increased in speed is the boundary between the crust and the mantle, where seismic waves start to travel through more dense rock.

Answer: When a seismic wave 'bounces backward' and reaches a boundary, it is called Reflection. Explanation: The seismic waves are the result of the landslides, earthquakes, volcanic eruptions, explosions by humans

When a seismic wave bounces backward when it reaches a boundary, it is called reflection. This phenomenon occurs when the wave encounters a change in medium or boundary, causing it to change direction and return to its source. Reflection is a key process in seismic imaging and is used to map subsurface structures in geophysics.
It is called seismic wave reflection. When a seismic wave encounters a boundary between different materials with contrasting density or rigidity, some of the wave energy is reflected back towards the source.

Reflection
When a seismic wave crosses a boundary between different materials, it may undergo reflection, refraction, or diffraction. Reflection occurs when the wave bounces off the boundary, while refraction causes the wave to change speed and bend as it enters a different material. Diffraction causes the wave to spread out as it encounters an obstacle or edge.
