The frequency and energy of most energetic of these photons is Hz and
J respectively.
The high energy photons will have least wavelength. Taking the given less wavelength for calculation of frequency and energy of photons.
λ = 2200 Å
Also, we know, 1 Å = m
So, λ =
λ = <em> </em>m
Now, calculating frequency using the formula -
c = fλ, where c is speed of light, f is frequency and λ is wavelength.
We know, c = m/s
f = c/λ
f =
frequency = Hz
Now, calculating Energy through the formula -
E = hf, where E is energy, h is planck's constant and f is frequency
Value of planck's constant = Js
E = *
Energy = J
Thus, frequency and energy of photons is Hz and
J respectively.

The answer is NH4Cl!
Ionic bonding=cation + anion
- the cation ammonium (NH4) has a single electron in its valence shell, and Chlorine needs a single electron to fill its valence shell, and they stick together.
Covalent bond= involves the sharing of electron pairs between atoms
- present in Ammonium ion between Nitrogen and Hydrogen atoms
