This is your perfect answer.

Ammonia reacts with copper(II)ions to precipitate light blue copper hydroxide. Ammonia causes the copper ion to go back into the solution as a deep blue ammonia complex. The precipitate dissolves as we add an excess of ammonia.

(b) Ozone absorbs radiation of wavelengths 2200–2900 Å, thus protecting organisms from this radiation. Find the frequency and en

GrogVix [38]

The frequency and energy of most energetic of these photons is $1.36*10^{15}$ Hz and $9.04*10^{-19}$ 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 = $10^{-10}$ m

So, λ = $2200*10^{-10}$

λ = $2.2*10^{-7}$ <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 = $3*10^{8}$ m/s

f = c/λ

f = $\frac{3*10^{8} }{2.2*10^{-7} }$

frequency = $1.36*10^{15}$ 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 = $6.63*10^{-34}$ Js

E = $6.63*10^{-34}$ * $1.36*10^{15}$

Energy = $9.04*10^{-19}$ J

Thus, frequency and energy of photons is $1.36*10^{15}$ Hz and $9.04*10^{-19}$ J respectively.
