Wavelength and Frequency Video Lessons

Concept: The Electromagnetic Spectrum

# Problem: The human eye contains a molecule called 11-cis-retinal that changes conformation when struck with light of sufficient energy. The change in conformation 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 164 kJ/mol.Calculate the longest wavelength visible to the human eye.
