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
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.
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.
The boundary separating the Earth's mantle and core is known as the core-mantle boundary. This boundary is characterized by a sharp decrease in seismic wave velocities, indicating a difference in composition and properties between the outer core and the lower mantle.
Seismic waves change speed and direction when they encounter changes in the density and composition of rocks. The Mohorovicic Discontinuity marks the boundary between the Earth's crust and mantle, causing seismic waves to abruptly change behavior when passing through it. By analyzing the way seismic waves interact with this boundary, scientists can infer the presence and properties of the Mohorovicic Discontinuity.

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.
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.
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.
