so and this problem. We have a table and we need to rank all the diameters that featured a emitter off this off this lens. And we know that the F number is just the Rachel off a focal end. Bye, the Future Day emitter. So if we want to rank all the lens we need to discover, do they emitter off each lens? So first of all, let's calculate the emitter off the lens. Hey, this is going to be 150. The limiters divided by one point two. This is going to be a growth, too warm, 100 and 30 millimeters. Did diameter off the lens be? It's just going to be, well, 50 limiters divided by 5.6. So this is equals two 27. That's we write this. It's going to be good with 20 seven millimeters and the diameter off the lens. See, it's just going to be 35 divided by 1.2. That's equal to you. 29 millimeters and let's put in here do the emitter of the lens D. So the diameter D it's just going to be 35 divided by 5.6. It's his equals two 6.3 millimeters. So? So let's see the answer to rank on Just the emitters. It's just going to be. Did I emitter off the sex? Followed by the diameter of B, followed by the diameter off? See? Follow? I did the immature off, eh? And this is the answer to this problem, that's all. Thanks for watching.
