White tern catches fish including crustaceans, flying fish, squid, and others. Prior of plunging into water, it hovers initially over the water surface and then either dives or dips in the surface, without getting entirely submerged into water, and catches its target.
The food or fish is captivated in its small, however, sharp black beak that is specific as it bent upwards and tapers to a sharp point. It also possesses a long slender body with tapering, long wings, all of which encourage its diving or dipping activity into the surface of the water.
Answer:
493.02 nm is the longest wavelength of light that will produce free chlorine atoms in solution.
Explanation:
,ΔH = 242.8 kJ/mol
Energy required to break 1 mole of Cl-Cl bond = 242.8 kJ
Energy required to break 1 Cl-Cl bond = E
Energy related with the wavelength of light is given by Planck's equation:
493.02 nm is the longest wavelength of light that will produce free chlorine atoms in solution.
