Answer : The energy of one photon of hydrogen atom is, 
Explanation :
First we have to calculate the wavelength of hydrogen atom.
Using Rydberg's Equation:

Where,
 = Wavelength of radiation
 = Wavelength of radiation
 = Rydberg's Constant  = 10973731.6 m⁻¹
 = Rydberg's Constant  = 10973731.6 m⁻¹
 = Higher energy level = 3
 = Higher energy level = 3
 = Lower energy level = 2
= Lower energy level = 2
Putting the values, in above equation, we get:


Now we have to calculate the energy.

where,
h = Planck's constant = 
c = speed of light = 
 = wavelength =
 = wavelength = 
Putting the values, in this formula, we get:


Therefore, the energy of one photon of hydrogen atom is,

Answer:
Squids = 450 - 490 nm (Moderate Frequency) (Blue)
Bees = 300 - 650 nm (Lower Frequency Bands)
Frogs = 280 - 580 nm (Very Low Frequency)
Explanation:
All of the above mentioned ranges are compared to that of humans.
I'm just surprised a little bit in the imagination that how these organisms see the world through their unique eyes. On the other hands, they are evolved like this just like we do so that may not be surprising enough. SIKE
