A parallel-plate capacitor with circular plates of radius 0.19 m is being discharged. A circular loop of radius 0.28 m is concen

tric with the capacitor and halfway between the plates. The displacement current through the loop is 2.6 A. At what rate is the electric field between the plates changing?

Answer:

\dfrac{dE}{dt}=2.59\times 10^{12}\ V/m.s

Explanation:

Given that

R= 0.19 m

r= 0.28 m

I= 2.6 A

We know that

I_D=\epsilon _oA\dfrac{dE}{dt}

A= Area of loop

dE/dt= rate of change of electric filed

I=Displacement current

Here r>R

So A=π R²

Now by putting the values

I=\epsilon _oA\dfrac{dE}{dt}

2.6=8.85\times 10^{-12}\times \pi\times 0.19^2\dfrac{dE}{dt}

\dfrac{dE}{dt}=2.59\times 10^{12}\ V/m.s

The shorter the wavelength of a photon, the greater its energy. We can see photons with wavelengths between 700 nanometers (red)
sveticcg [70]

Answer: from 0.66 eV to 13 eV

Explanation: In order to justify this range of energy corresponding to the spectrum of hydrogen we firrsly have to consider the model given by Planck to describe this kind of atoms. On the hand the spectral series resume the main atomic transtitions corresponding for the hydrogen.

The attached file gives more details about these considerations.
