Answer : The wavelength of photon is, 
Explanation : Given,
Energy of photon = 
Formula used :

As, 
So, 
where,
= frequency of photon
h = Planck's constant = 
= wavelength of photon = ?
c = speed of light = 
Now put all the given values in the above formula, we get:


Conversion used : 
Therefore, the wavelength of photon is, 
Explanation:
1. Height Relatives to reference point, Mass, and strength of the gravitational field it's in
2. Distance in the magnetic field
I have one reason the reaction take place faster because the molecules are going at a faster pace because the temperature is rising
