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)

725 nm The energy needed for a single molecule to change will be the energy for a mole to change divided by avogadro's number, so 165000 / 6.022 x 10^23 = 2.74x10^-19 J The energy of a photon is expressed as E = hc/l where E = energy h = Planck constant (6.626070040Ă—10^â’34 Js) c = speed of light (299792458 m/s) l = wavelength Now solve for l E = hc/l El = hc l = hc/E Now substitute known values. l = hc/E l = 6.626070040Ă—10^â’34 Js * 299792458 m/s / 2.74x10^-19 J I = 7.25x10^-07 m l = 725 nm

Yes violent video games can increase the risk of the person wanting to try out the things in reality , in real life . the person may be mad and want revenge and is playing the video game and the video may give more ideas of what to do sounds confusing but yes it does increase the influence sadly on violence out there . there is much evidence of many incidents where violence has happened sadly , like the columbine school shooting on april 20 of 1999 r.i.p to the innocent lives lost may they rest in peace ❤️also violent video games you can choose your choices on who to shoot and what to do and what to do not to get caught like gta 5 no hate on it i'm personally a big fan but you can choose to do bad or good on the game just like real life. people might illusion it in real life n try it out because in the video game it seems so realistic.
