The shorter the wavelength of a photon, the greater its energy. We can see photons with wavelengths between 700 nanometers (red)
and 400 nanometers (violet), which correspond to energies of 1.8 to 3.1 electron volts (eV). Which photon energies make up the spectrum of hydrogen?
1 answer:
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.

Answer:OB=58.3m
Explanation:
So here cow wanders 30m in north and turns 22 degrees in right side and moves 40m more, as shown in figure given.
now take the starting point as a origin such that cow moves in x-y co-ordinate axis.
As shown in figure length OA is the length when cow moves in north or y direction. Later she takes 22 degrees turn to right and moves 40m more.
So the final displacement is the length of cow from the origin that is length OB.
now co-ordinates of B are [40cos22°,40sin22°+30] i.e [37.084,44.984]
now displacement of cow= length of OB
=
=
OB =
