This ideal material is called "black body".
When visible light strikes an object, it can be absorbed, transmitted, or reflected. The color of the object is determined by which wavelengths of visible light are reflected back to our eyes. Objects that appear white reflect most of the visible light, while objects that appear black absorb most of the visible light.
The sun emits visible light most strongly, which is the type of light that is visible to the human eye.
Most of the EM spectrum is visible light.
visible light
No
The blue part of the spectrum has more energy than the red part.
red and violet
No, EXCEPT for the element Radium, which gives of its own blue green glow. The radioactivity of most radioactive substances is not visible to the human eye and therefore abscess of fluorescence does not mean that the substance is not radioactive.Fluorescence is normally caused when a substance absorbsthe energy form an invisible part of the light spectrum (eg UV light) and then re-emits it in the visible spectrum. The substance then seems to glow (fluoresce) with more light than is falling on it and thus stands out vividly.
Most of the electromagnetic spectrum is not visible.
Most of the electromagnetic spectrum is not visible.
Visible light can be absorbed anywhere.-- Anything that appears to have a color in sunlight has absorbed most ofthe visible light of all other colors.-- Anything that appears black in an otherwise light room has absorbed all ofthe visible light that fell on it.
Ultraviolet light has the most energy among visible light, followed by visible light, then infrared light. This is because the energy of a photon is inversely proportional to its wavelength, with shorter wavelengths having higher energy. Ultraviolet light has shorter wavelengths than visible light, making it more energetic.
