<u>Answer:</u>
<u>For A:</u> The energy of the given amount of photons for infrared radiation is 
<u>For B:</u> The energy of the given amount of photons for infrared radiation is 
<u>For C:</u> The energy of the given amount of photons for infrared radiation is 
<u>Explanation:</u>
The relationship between energy and frequency is given by Planck's equation, which is:
......(1)
where,
h = Planck's constant = 
E = energy of the light
c = speed of light = 
= wavelength of light
= Avogadro's number = 
n = number of moles of photons = 1.70 moles
Conversion factor used: 
Wavelength of infrared radiation = 
Putting values in equation 1, we get:

Hence, the energy of the given amount of photons for infrared radiation is 
Wavelength of visible light = 
Putting values in equation 1, we get:

Hence, the energy of the given amount of photons for infrared radiation is 
Wavelength of ultraviolet radiation = 
Putting values in equation 1, we get:

Hence, the energy of the given amount of photons for infrared radiation is
