Explanation:
Given that,
The frequency of electromagnetic spectrum is 
(A) Let the wavelength of this radiation is
. We know that,

So, the wavelength of this radiation is
.
(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :

h is Planck's constant

1 kcal = 4184 J
It means,

Hence, this is the required solution.
Photosynthesis is when a plant takes in carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere also creating sugar (glucose), it is so important for humans and animals because it provides the basic energy source for virtually all organisms
Answer see because there is a lack of potassium peanuts and walnuts also help the gravitational pull moons rocks different one but because of this energy conversion is the after effect of the camera being shot
