Infrared radiation heats up the pit membrane tissue, and TRPA1 channels open when a threshold temperature is reached, allowing ions to flow into the nerve cells and triggering an electrical signal.

In this paper, we discussed the transition selection rule of electrical dipole radiation in atom physics by the parity theory and angular momentum theory in quantum.

Its role is to the sun's radiation is converted to electrical energy stored in batteries or sent to them, or to promote the work load.
