Answer:
The energy can be used in a redox reaction
Explanation:
When electrons in photopigments become excited, what is the result of the energy input?
The energy can be used in a redox reaction. The energy can be transferred to a nearby pigment. They can cause fluorescence or heat emission

The complete question is as follows: Barium chloride (BaCl2) emits a green color when flame tested. What can be said about the wavelength of light it emits? Select all that apply.
A) The thermal energy is transferred to the outer electrons of the barium ions.
B) The electrons gain enough energy to excite them to a higher energy level.
C) The electrons drop back down to their ground state, gaining energy.
D) The electrons release energy emitting a wavelength of 500-560 nm, corresponding to a green light, when going back to their ground state.
Answer: The following can be said about the wavelength of light that Barium chloride emits:
- The thermal energy is transferred to the outer electrons of the barium ions.
-
The electrons gain enough energy to excite them to a higher energy level.
- The electrons release energy emitting a wavelength of 500-560 nm, corresponding to a green light, when going back to their ground state.
Explanation:
As barium chloride is emitting green color when flame tested. This means that thermal energy is being transferred to the outer electrons of barium ions.
A visible light is emitted by a substance when its electrons move from a region of higher energy level to lower energy level. This is because energy is given off by the electrons when they move in a lower region.
This is only possible when the electrons gain enough energy to excite them to a higher energy level.
Also, the electrons release energy emitting a wavelength of 500-560 nm, corresponding to a green light, when going back to their ground state.
Thus, we can conclude that following can be said about the wavelength of light that Barium chloride emits:
- The thermal energy is transferred to the outer electrons of the barium ions.
-
The electrons gain enough energy to excite them to a higher energy level.
- The electrons release energy emitting a wavelength of 500-560 nm, corresponding to a green light, when going back to their ground state.
