1.The primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of nature.
2.absorbation of light.
Waves can be absorbed at the boundary between two different materials. When waves are absorbed by a surface, the energy of the wave is transferred to the particles in the surface.
3.The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. ... Notice that as the distance increases, the light must spread out over a larger surface and the surface brightness decreases in accordance with a "one over r squared" relationship.
heat
1.Heat is the form of energy that is transferred between systems or objects with different temperatures (flowing from the high-temperature system to the low-temperature system). Also referred to as heat energy or thermal energy. Heat is typically measured in Btu, calories or joules.
2. The factor or condition that is necessary for heat transfer to occur is that two object 'must have different temperature'. Heat always flow or move from the hotter object to the cooler one. ... Heat Transfer can occur in three ways: Conduction, Convection, and Radiation.
