What materials Cannot reflect light?
There is no material that does not reflect light. The material that comes closest is Vantablack from the UK’s Surrey NanoSystems . Vantablack absorbs most EM radiation over a broad swath of the infrared, visible, and ultraviolet spectrum, but it does not absorb 100\%.
What an opaque object does to light waves that are not absorbed?
If the object is opaque, then the vibrations of the electrons are not passed from atom to atom through the bulk of the material. Rather the electrons of atoms on the material’s surface vibrate for short periods of time and then reemit the energy as a reflected light wave.
Which object does not reflect more light?
Answer: Rough surfaces and black , dark objects.
Which of the following does not use reflection of light?
endoscope does not work on the principle of total internal reflection. Explanation: The total internal reflection takes place because the light is passing from a medium having high refractive index that is water to Air which has a lesser refractive index.
When an opaque object comes in the way of light it makes?
Shadows are formed when an opaque object comes in path of light. Shadows are formed because light travels in a straight line and it can’t pass through an opaque object.
What is the difference between opaque materials and translucent materials?
Opaque materials either reflect or absorb any incident light. As a result, light rays cannot pass through opaque materials. Wood, stone, etc. are opaque materials. Translucent materials allow partial transmission of light through them.
Why are some objects opaque/black?
I understand why objects are opaque/black. For example when ( white) light is incident on a closed book ( let’s say it’s blue ), all wavelengths of visible light except blue are absorbed and hence we see it as blue. [0.] it is the electrons that absorb the ( non-blue) photons from the white light and jump to higher energy states.
Which object can be seen through a transparent material?
Any object can be seen through a transparent material. One example of transparent material is pure glass. Opaque materials either reflect or absorb any incident light. As a result, light rays cannot pass through opaque materials.
What happens to the incident light rays of opaque objects?
Reflection: The incident light rays may get reflected at the surface of an opaque object. The objects appear as colored because of the reflection of a particular wavelength. The rest of the wavelengths get absorbed or scattered. Common examples of opaque objects are wood, stone, metals, concrete, etc.
