<u>Answer:</u> The correct answer is Option c.
<u>Explanation:</u>
pH is the measure of acidity of the solution. It is known as power of hydrogen. It is measured in a scale from 0 to 14. The solutions having pH from 0.1 to 6.9 is known as acidic solution, the solution having a pH of 7.1 to 14 is known as basic solution. The solution having pH 7 is known as neutral solution.
Nitric acid is a strong acid because it completely dissociates into its respective ions. The pH of this solution is very low.
Sodium hydroxide (NaOH) is a strong base because it completely dissociates into its respective ions. The pH of this solution is very high.
When a solution of low pH reacts with a solution of high pH, it results in the solution having a neutral pH which is 7.
Hence, the correct answer is option c.

Wavelength of the light is 2.9 × 10⁻⁷ m.
<u>Explanation:</u>
Planck - Einstein equation shows the relationship between the energy of a photon and its frequency, and they are directly proportional to each other and it is given by the equation as E = hν,
where E is the energy of the photon
h is the Planck's constant = 6.626 × 10⁻³⁴ J s
ν is the frequency
From the above equation, we can find the frequency by rearranging the equation as,
ν = =
Now the frequency and the wavelength are in inverse relationship with each other.
ν × λ = c
It can be rearranged to get λ as,
λ = c / ν
=
So wavelength is 2.9 × 10⁻⁷ m.
