The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 165 kj/mol. calculate the longest wavelength of light visible to the human eye. (avogadro’s number is 6.022 x 1023 units/mole)
