Answer:
atoms or molecules
Explanation:
Gas particles are constantly bumping into each other and the borders of their container.
<u>Answer:</u> The energy of one photon of the given light is 
<u>Explanation:</u>
To calculate the energy of one photon, we use Planck's equation, which is:

where,
= wavelength of light =
(Conversion factor:
)
h = Planck's constant = 
c = speed of light = 
Putting values in above equation, we get:

Hence, the energy of one photon of the given light is 
S2F6, is the correct answer I believe!
