What happens to energy as frequency increases on the electromagnetic spectrum?
gladu [14]
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. ... Mechanical and electromagnetic waves with long wavelengths contain less energy than waves with short wavelengths.

Helen [10]

Complete Question

Consider a system consisting of an ideal gas confined within a container, one wall of which is a movable piston. Energy can be added to the gas in the form of heat by applying a flame to the outside of the container. Conversely, energy can also be removed from the gas in the form of heat by immersing the container in ice water. Energy can be added to the system in the form of work by pushing the piston in, thereby compressing the gas. Conversely, if the gas pushes the piston out, thereby pushing some atmosphere aside, the internal energy of the gas is reduced by the amount of work done.

          pV=nRT

so the absolute temperature T is directly proportional to the product of the absolute pressure p and the volume V,Here n denotes the amount of gas moles,which is a constant because the gas is confined and R is the universal constant

What is the \triangle U as the system of ideal gas goes from point A to point B on the graph recall u is proportional to T

Answer:

\triangle T=0

\triangle V=0

The gas A and B have same internal energy

Explanation:

From the question we are told that

Pa=u atm\\Va=1m^3\\Pb=1 atm\\Vb=4m^3

Generally the equation of temperature is mathematically given as

Ta=\frac{Pv}{nR}

Ta=\frac{u*1}{nR}

And

Tb=\frac{PbVb}{nR}

Tb=\frac{u*1}{nR}

Generally the change in temperature \triangle T is mathematically given as

\triangle T=Tb-Ta=Tb=\frac{u*1}{nR}-\frac{u*1}{nR}

\triangle T=0

Generally the change in internal energy \triangle V

\triangle V=nC_v \triangle T\\

\triangle V=0

Therefore with

\triangle T=0

\triangle v=0

The gas A and B have same internal energy
