what is the difference between seismic reflection and refraction?
481850
Reflection seismic is when seismic waves reflect (bounce) from geologic layers. The seismic profiles made from this data are a reflection (pun intended) of the geologic layering. ... Refraction seismic records waves that bend through the earth (refract) before returning to the surface to be recorded.

Reflection and total internal reflection are physical properties of waves. Reflection occurs in all kind of waves, but total internal reflection occurs only with light rays. Total internal reflection occurs when light passes through denser medium to the lighter medium.

Reflection, on the other hand, is broader. ... Reflective practice is more focused on professional practice, but reflection is relevant to all aspects of living. Many writers also make a distinction between reflection and critical reflection (Fook and Askeland 2006a).

2. Time difference btw original sound and echo must be 0.1s. when sound is incident on the surface of a medium it bounces back into the first medium this phenomenon is called reflection of sound but now if we apply some conditions on reflection of sound then it will become echo the conditions are: 1.

1.8 Reflection, Transmission and Absorption. Reflection is the process by which electromagnetic radiation is returned either at the boundary between two media (surface reflection) or at the interior of a medium (volume reflection), whereas transmission is the passage of electromagnetic radiation through a medium.

14. What is the difference between the focus and epicenter of an earthquake? The focus is the point within the earth where seismic waves originate; it is centered on the part of the fault that has the greatest movement. The epicenter is on the earth's surface directly above the focus.

The electromagnetic waves constituting light are refracted when crossing the boundary from one transparent medium to another because of their change in speed. A straight stick appears bent when partly immersed in water and viewed at an angle to the surface other than 90°.

Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings. The amount of diffraction increases with increasing wavelength.

regular reflection : it is when parallel rays of light fall on a smooth surface and reflect parellely. irregular reflection : it is when parallel rays of light fall on a rough surface and reflect in different directions.

As nouns the difference between shadow and reflection is that shadow is a dark image projected onto a surface where light (or other radiation) is blocked by the shade of an object while reflection is the act of reflecting or the state of being reflected.

Geometric optics is when we treat light as a single beam (A ray) and study the properties. ... Maxwell's electromagnetic theory put the wave theory of light on a very firm footing. It is to be noted that reflection and refraction are explained by physical optics as well. That's the basic difference was this.

The phase difference between incident wave and reflected wave is 180∘ when light ray. Solution : When light reflect from denser surface phase change or π occurs.

Only a part of the total energy in the light is reflected during the normal reflection. Part of it is scattered and part of it is refracted. In total internal reflection all the light is reflected.

Reflection is flipping an object across a line without changing its size or shape. ... The translation is sliding a figure in any direction without changing its size, shape or orientation.

This is rotational symmetry. While the shape appears the same as the reflection, the process to get there is different. The difference between the two, then, is the in the way the object is moved or transformed to get to the result.

As nouns the difference between earthquake and quake is that earthquake is a shaking of the ground, caused by volcanic activity or movement around geologic faults while quake is a trembling]] or [[shake|shaking.

The angle of reflection of a ray or beam is the angle measured from the reflected ray to the surface normal. From the law of reflection, , where is the angle of incidence. is measured between the ray and a line normal to the surface that intersects the surface at the same point as the ray.
