WebThe group velocity v g is defined by the equation: where ω is the wave's angular frequency (usually expressed in radians per second), and k is the angular wavenumber (usually expressed in radians per meter). The phase velocity is: v p = ω/k.. The function ω(k), which gives ω as a function of k, is known as the dispersion relation.. If ω is directly proportional … WebRefraction is caused by the change in speed experienced by a wave when it changes medium. In Lesson 1, we learned that if a light wave passes from a medium in which it …
Web11. aug 2024 · There are two types of seismic surveys Refraction ie 'critical refraction' which is useful for determining velocities of layers Reflection, which is useful for determining … Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media, labeled , and so on, are used to represent the factor by which a light ray's speed decreases when traveling through a refractive medium, such as glass or water, as opposed to its velocity in a vacuum.

Web13. apr 2016 · I know that the group velocity of a light pulse is defined as. (1) v g = v p ( 1 + λ n d n d λ) = c n ( 1 + λ n d n d λ). On the other hand, it is also defined as. (2) v g = c ( n − λ d n d λ) = c n ( 1 − λ n d n d λ) − 1. That leads to the equation. (3) 0 = λ 2 n 2 ( d n d λ) 2. After neither λ nor n is 0, does that mean that ...
