WebCorrect option is C) Ray optics is valid when characteristic dimension are much larger than wavelength of light . The size of obstacle must be much larger than the wavelength of light. If wavelength is comparable to the size of object, then diffraction could happen, but it cannot be explained using ray optics, it will require wave theory of light. WebOct 23, 2024 · 50.

In this work, a tomography method, namely full-field cross-interface computed tomography (FCICT), is proposed to solve confine-space problems. The FCICT method … WebGeometrical optics (ray optics) describes light propagation in the form of geometric rays. Here, the paraxial approximation means that the angle θ between such rays and some reference axis of the optical system always remains small, i.e. ≪ 1 rad. Within that approximation, it can be assumed that tan θ ≈ sin θ ≈ θ.The evolution of beam offset … imdb radiohead
