<u>Answer:</u> The energy of one photon of the given light is
<u>Explanation:</u>
To calculate the energy of one photon, we use Planck's equation, which is:
where,
= wavelength of light =
(Conversion factor:
)
h = Planck's constant =
c = speed of light =
Putting values in above equation, we get:
Hence, the energy of one photon of the given light is
Answer:
Explanation:
At constant pressure Thermal energy always moves from a greater energy level to a lesser energy level, laws of thermodynamics prove that.
Nature always likes to attain equilibrium either it's movement of heat energy or flow of water from higher region to lower region. The first and second law of thermodynamics are profe of that, the first law says that the total energy of universe is Constant. Energy can not be destroyed it always changes from one form to another, by work and heat. The second law explains why thermal energy moves from a greater energy level to a lesser energy level, it deals with the change in entropy of a system and surrounding and states heat flows from hot environment to cold environment.
