The intensity of the incident light is very similar to that transmitted and that explains why they are usually not so prone to heat up. The transparent bodies they are those that let through almost all the light that falls on them. The aluminumFor example, it is opaque in the frequency range of visible light, but is completely transparent in the frequency of ultraviolet rays. On the other hand, the transparency condition and opacity depends in most cases on the energy (or frequency) of the light that falls on an object. The object behavior with respect to photons it is not binomial and sometimes phenomena such as reflection of light (the change of direction that occurred at the separation surface) or refraction (the change in speed when passing from one material medium to another) can occur. On the contrary, when it comes to transparent objects, the leap they have to make to be absorbed is not possible and the photons go through the object in search of new electrons to excite. The transfer of energy is what explains why objects do not let light pass through, but they heat up the more intense this energy is: in this sense, dark objects are more likely to absorb photons than light ones.

The star nearest Earth is the Sun.The difference, precisely, lies in the moment in which the photons try to pass the energy: opaque objects succeed and, therefore, the photons are “consumed”. It's obvious that humans will never travel to planets near even the closest stars. So, when you see the Sun, you aren't seeing it as it is.

This further lead to the establishment of a cause and effect relationship.

Scientists make use of this experiment so to gain excessive access to extraneous and independent variables.

Why scientists conduct controlled experiments

Controlled experiment helps in eliminating significant uncertainty in a potential test result.

Controlled variables are ones that could affect the experiment, and to avoid that occurrence, scientists make them constant to further avoid an unfair experiment. A variable can be said to be a trait, factor and condition.ĭuring a controlled experiment, an independent variable can be manipulated and the dependent variable is measured while unrelated variables are controlled. That particular variable is termed independent variable. Further ExplanationĪdditionally, a controlled experiment is a scientific test which is usually done under some controlled condition which means only a few factors are changed at a given time while the rests are kept constant.įurthermore, controlled experiments are carried out to examine whether a particular variable is capable of causing a change in another variable. This type of experiment allows only one variable to ever change at a given time. Controlled experiment is the type of experiment that involves changing only one variable at a time.Ĭontrolled experiment is subtly defined as an experiment which holds everything constant except one particular variable.
