And this is f2.

And it's for focus.

We have focused on the worst case scenario.

Adjust the microscope's focus.

Set the focus of the microscope.

Adjust the focus of the microscope.

It's not a this is wonderful!

Focal length of the lens

Well, we just used the distance formula.

Or they can be, I don't want to say always.

Just focus.

Bifocals.

Your focus,

And hard to keep focus.

And what we want to do is, we want to find out the coordinates of the focal points.

We also know that the projection of the building on the internal chip is 4mm in size.

Telescope focal length

Eyepiece focal length

So let's call that a directrix.

That's our directrix and it has the equation y is equal to k.

That's an engineer gazing at tube number 36, trying to figure out why the memory's not in focus.

35mm equivalent focal length

That's this distance right there.

And that's what we set out to figure out in the beginning.

And you enter that space, and you feel like, Wow!

Requires great focus.

We focus on Parker. And move it.

Let's focus on the conversations between our friends and our family and our coworkers and our loved ones.

And it's a center, a focal point for economic and social development.

So, that's because the camera needs time to calculate the focus and exposure, but if you pre focus with a half press,

Well, the first thing you do is though I've never well, we could just figure out the focal length just by plugging into the formula.

So you know that a is equal to x1.

So let's solve for the focal length.
