Sagot :
The energy (in j) of one photon of this radiation is [tex]2.518*10^{-23}[/tex]J
Given,
frequency = 3. 8 x [tex]10^{10}[/tex] hz, h = Planck's constant = 6.626*[tex]10^{-34}[/tex]Js
E=frequency*Planck's constant=3. 8 x [tex]10^{10}[/tex] hz*6.626*[tex]10^{-34}[/tex]Js=[tex]2.518*10^{-23}[/tex]J
Energy
In physics, energy is the quantifiable attribute that is transferred to a body or to a physical system, and it can be seen as heat and light as well as while work is being done. The law of conservation of energy asserts that although energy can change its form, it cannot be created or destroyed. Energy is a conserved quantity. The International System of Units (SI) uses the joule as the unit of measurement for energy, which is defined as "the energy transferred to an object by the work of moving it a distance of one metre against a force of one newton."
A radio wave has a frequency of 3. 8 x 1010 hz. what is the energy (in j) of one photon of this radiation? (use scientific notation in your answer: 1. 0e29)
