This multi -part question starts by asking us if a complex absorbs light at 610 nanometers, what color would you expect that complex to be? so if you have something that absorbs at 610, that means it absorbs orange light.
00:28
And therefore, the complex based on the color wheel, the color would be, let's see, color would be blue.

Part b asks us what the energy in jewels of a photon with a wavelength of light with 610 nanometers would be.
00:58
And for that, we need to know the equation for energy, which is e equals hc over lambda.
01:08
And there's a couple different versions of this equation, where e equals energy, and this correlates energy to wavelength or lambda, where h is planck's constant of 6 .626 times 10 to the minus 34 joules second.
01:25
And c is the speed of light, which is 3 .00 times 10 to the 8 meters per second.
01:32
And so we can calculate energy by putting in these values, 6 .626 times 10.
01:44
To the minus 34, and that is dual second, parentheses, times the speed of light, which is 3 .00 times 10 to the 8th.
02:00
And that's meters per second.
02:04
And with that, our seconds cancel here.
