When light is incident on a black body?
When light is incident on a black body, it is mostly absorbed rather than reflected. This absorption results in an increase in the body's temperature. The body then emits thermal radiation, with the amount and wavelength of this radiation being determined by the body's temperature.
What happen when lights strikes an object in black cloth?
When light ray strikes a black object (it does not matter if it is cloth or solid) some of the light is 'absorbed' and some of it is reflected back to the normal of the surface (pependicular). Reflected light continues its path and absorbed light is transormed usually into heat. For example if you leave black and white objects in the desert they will heat but the black one will reach higher temperature. In physics there is an idealistic object called 'perfect black body' and the light which hits it is not reflected but absorbed. This means ALL of the incoming light is transformed into heat and the scientist use this imaginary object to calculate the emission of this body. This is called 'heat emission of a perfect black body'.
What will happen when white light falls on an object which does not transmit light?
when white light falls on a body which doesnot transmitts light the either all the light is absorbed by body as like black body and stored it in another form of energy or all the light may get reflected as like white body.
Is there any substance or instrument that can absorb a light?
Most everything light shines on absorbs some of the light. Some of the light is reflected. A black body is the best absorber of light since it reflects none of the energy.
If your body is a black hole are you invisible?
Black holes are invisible to the visible light spectrum and many others because their gravity is so strong it pulls in even light. So in theory yes. But a human body is FAR too light to ever form a black hole. However, if you define visibility as human perception of it, while we never see light from a black hole, we would notice the absence of light in an area, so even if it were possible to turn your body into a black hole, no one would see you, but the would see a black gap in space where you should be...
What wave length light is reflected from a red shirt?
the wavelength of red light i.e. 700 nm is reflected from red shirt. this follows the fact that a body absorbs those light radiations which it does not contain and reflects the ones it contains. eg. the red t shirt would absorb a green or a blue radiation but when red light falls on it, it gets reflected.
What is the term that refers to the amount of light a body reflects?
The term is "albedo," which is a measure of the reflectivity of a surface or body, indicating how much incoming light is reflected back. A high albedo means more light is reflected, while a low albedo means more light is absorbed.
Percentage of light reflected by the moon is known as?
. . . or from any heavenly body is called albedo.
What color is a Monarch butterfly's chrysalis?
A yellow, white, and black striped caterpillar with 4 filaments coming off at the ends of its body
What is an illustration of light being reflected?
When light hits your body it reflects off your body, if it didn't then you wouldn't be able to see your self.
Why shinnig objects get the less amt of heat?
Heat is a form of energy and like light may be reflected or absorbed. Shining bodies (sometimes called white body) reflects most of this energy so will not get as hot as darker objects (black body)
What happens when heat goes through black objects?
For a black objects or black body, the light is absorb to the black body not going through. The absorbed light is transformed to thermal energy inside the object.
