Web5. mar 2024 · A beam of light of wavelength λ 1 is approaching a glass block from the left at speed v 1. The dashed lines represent the wavefronts. Ray A reaches the block first, at P. A wavelet is generated at P, moving with speed v 2. The drawing is made for the instant when ray B reaches the point Q. WebThe law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in …

WebTyler Chan 702 Luster is a property that describes how light is reflected on the surface of a mineral. There is 2 types of Luster which is Metallic which looks like polished metal and nonmetallic which does not look like polished metal. An example of Metallic luster is pyrite and an example of nonmetallic luster is Cinnabar. Cleavage- sharp division; a split.

Web25. jan 2024 · Reflection at Plane Surfaces: When a ray of light is incident on a plane surface, it bounces off the object. This phenomenon is called reflection. Basically, due to reflection, we can look at the object and get to know its colour. When white light falls on an object, it absorbs all the colours in it and only reflects back some colours. Web14. mar 2012 · Types of reflection. Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection. WebFor example, a gem-quality emerald is a deep green color. This is because it is reflecting the green wavelengths of light to our eyes, and is absorbing the other visible wavelengths of light. Emerald is the mineral beryl, but it is trace Cr 3+ in the mineral structure that causes the green color. how to download files from huggingface
