    Science (Total 11 subjects must be studied for science students). [25] In class 9–10 and 11–12, each has its own pre-selected set of subjects with one optional subject which can be changed. For instance, a student studying in science group can't replace chemistry, Bangla or religion for accounting or history.

    en.wikipedia.org/wiki/Eleventh_grade

    In India, the 11th Grade is the first year of higher secondary education and is often considered the third year of high school (Higher/Senior Secondary School or Senior High School). It is commonly known as "Class 11" or "Plus 1" (derived from "10+1") and, in some states, as the first year of Junior College (Intermediate or Pre-University Course).

  4. Reflection (physics) - Wikipedia

    en.wikipedia.org/wiki/Reflection_(physics)

    Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface.In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p (TE and TM) polarizations is fixed by the properties of the media and of the interface between them.

  5. Diffuse reflection - Wikipedia

    en.wikipedia.org/wiki/Diffuse_reflection

    Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.

  6. Transparency and translucency - Wikipedia

    en.wikipedia.org/wiki/Transparency_and_translucency

    Diffuse reflection is typically characterized by omni-directional reflection angles. Most of the objects visible to the naked eye are identified via diffuse reflection. Another term commonly used for this type of reflection is "light scattering". Light scattering from the surfaces of objects is our primary mechanism of physical observation. [3] [4]

  7. Specular reflection - Wikipedia

    en.wikipedia.org/wiki/Specular_reflection

    Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface. [ 1 ] The law of reflection states that a reflected ray of light emerges from the reflecting surface at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by ...

  8. Reflection phase change - Wikipedia

    en.wikipedia.org/wiki/Reflection_phase_change

    Light waves change phase by 180° when they reflect from the surface of a medium with higher refractive index than that of the medium in which they are travelling. [1] A light wave travelling in air that is reflected by a glass barrier will undergo a 180° phase change, while light travelling in glass will not undergo a phase change if it is reflected by a boundary with air.

    In its positive form, the background light is instead phase-shifted by +90°. The background light will thus be 180° out of phase relative to the scattered light. The scattered light will then be subtracted from the background light to form an image with a darker foreground and a lighter background, as shown in the first figure. [5] [6] [7]
