"Light is a form of energy called electromagnetic radiation, which is a wavelength that is visible to a human eye". When light hits a surface, it can either be transmitted through it, reflected, or absorbed (Pearson Science, 2012). The importance of this investigation is to see how each color can react to a light source.
The aim of this experiment is to investigate the rate of absorption of light according to the different colored surfaces.
The reason that we are able to see everything is because of visible light. Light moves as a wave, bouncing off of objects so that we can see them. Without it we would be in complete darkness (live science, 2017). When you shine light onto an object, a number of things can occur, such as transmission, refraction, and absorption. Transmission is the process where light waves move all the way through a material without getting absorbed. This can occur with transparent or semitransparent materials, such as glass. Refraction is when light bounces off of a surface. Suppose the light reflects off a smooth surface, such as a window. It will produce a clear image (bray may the science guy, 2016). However, if the light reflects off a rough object, then the light will reflect in multiple directions and will not form an image. This is called diffuse reflection. The process of absorption is when light is converted into another form of energy and is absorbed into another substance.
Electromagnetic radiation is a form of energy that is in substances all around us, such as Radio waves, Gamma waves, microwaves, X-rays, and the sun. Visible light is only a small portion of electromagnetic radiation. Radiation in the Electromagnetic spectrum is often characterized by wavelengths. The shorter the wavelengths mean the highest amount of energy, which can also be quite dangerous. Longer wavelengths contain lower amounts of energy and is usually less harmful (bcscince, 2017). Ultraviolet is a type of electromagnetic radiation, it is produced by the sun and some artificial sources. Ultraviolet radiation is the leading cause of sunburn, eye damage, aging skin, and skin cancer. Although it also has some useful benefits, as it is a natural source of vitamin D. Inferred radiation is a part of the three ways in order to transfer heat from one substance to another; the other ways are convection and conduction.
"Emittance is the measurement of a surface's ability to radiate heat. It can occur when an object creates some form of electromagnetic radiation". Everything in the world emits some kind of radiation. The amount of emission that a substance has depends on its temperature (Kind of Energy, 2008).
In this experiment, the coloured can that is believed to absorb the most heat will be the black can. This is because black absorbs all of the colors of light instead of reflecting it like lighter colors. This is why the white can have water that will reach a lower temperatu...
