Colored chemicals, or pigments, used to draw a tatoo, absorb more light than the unpigmented skin. If they absorb enough light this will heat them to the point that they will decompose into simpler chemicals, which will not be colored, and hence, the tatoo will be erased.
No!! Light beams of photons do not interfere with one another except in crystals as phonons.
a type of light, from a beam of light
A LASER, or Light Amplification by Simulated Emission of Radiation, and is made by causing a particular substance to emit photons, almost all of which are one wavelength. A flashlight, however, uses a light bulb, which emits light due to the filaments, and will spread out. Both, however, are forms of light.
A beam of light is a broad, focused stream of light, while a ray of light is a narrow, straight path that light travels in. The beam carries more energy and can illuminate a larger area, while a ray is a simplified representation of how light propagates in a specific direction.
Polarizing a beam of light is simply accomplished by passing the light through a polarizing filter. The polarizing filter will permit only light of a given polarization (or polarity) to pass through it. There are several different types of polarization, but they affect similar results. Use the links and check out the pictures.
I believe you are referring to a laser beam.
laser.
When a strong beam of light is passed through a colloidal solution, then scattering of light is absorbed.
A coherent beam refers to a beam of light in which the electromagnetic waves are in sync and have a constant phase relationship. This results in the waves reinforcing each other, producing a single, strong beam of light. Lasers are an example of a coherent beam source.
A laser is a beam of very strong and focused light. It is possible for this light to damage the retina of your eye permanently, and you will lose all or part of your vision.
scattered light
A beam of light is simply referred to as light or a light beam.
No!! Light beams of photons do not interfere with one another except in crystals as phonons.
Another name for the beam of light from a flashlight is a "light beam" or "beam of light."
a type of light, from a beam of light
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
A ray is a narrow beam of light.
