Newton’s Corpuscular Theory Of Light

The Theory corpuscular light Newton (1704)  proposes that the light material consists of particles that Isaac Newton called corpuscles. These particles are thrown in a straight line and at high speed by different sources of light (the Sun , a candle, etc.). In physics  light is defined as a part of the radiation field called

What Is An Isothermal Process? (examples, Exercises)

The isothermal or isothermal process is a reversible thermodynamic process in which the temperature remains constant. In a gas, there are situations in which a change in the system does not produce variations in temperature, but does in physical characteristics. These changes are the phase changes, when the substance changes from solid to liquid, from

Transmittance: What It Is, Molecular Energy Diagram And Exercise

the transmittance Optical is the quotient between the emergent luminous intensity and the incident luminous intensity on a sample of translucent solution that has been illuminated with monochromatic light. The physical process of the passage of light through a sample is called light transmission  and thetransmittance it is a measure of light transmission. Transmittance is an

Pleiades: History, Origin And Composition

The PleiadesThey are an open cluster of stars, visible to the naked eye in the night sky in the constellation Taurus. The members of an open star cluster are linked through the force of gravity and originate from the same molecular cloud. With the naked eye most observers distinguish six stars, although exceptionally people with

Thermal Dilation: Coefficient, Types And Exercises

The thermal expansion  is increased or variation of various metric dimensions (such as length or volume) that undergoes a physical object or body. This process happens due to the increase in temperature surrounding the material. In the case of linear dilation, these changes occur in only one dimension. The coefficient of this expansion can be
