00:02 So in this question it says that the human eye can detect light at frequency of 7 .34 times 10 exponential 14 hertz in the visible region of this spectrum.
00:13 We need to calculate the energy in joules of an individual photon of this light.
00:18 So let's solve it.
00:20 So we know that energy e is equal to our planck constant times our frequency.
00:28 So in the equation our frequency is giving us 7 .34 times 10 exponential 14 hertz and then our planck constant a is equal to 6 .602 times 10 exponential minus 34 joule per second...
