Next, we get into "Apo-ness."This is where we measure the exact amount of energy from the different colors goes into the Airy disk of a star. In the above example, the red and blue were not particularly well co
Define negative magnification. What does it mean when a magnification is less than 1 in magnitude? What is meant by a negative magnification? What is meant by a magnification that is less than 1 in magnitude? Explain why shape of high s...

That's the appeal of triple-leveraged (3x) exchange-traded funds (ETFs), investments that aim to triple the returns of the markets they track. But this magnification of gains has a flip side that some investors don't fully grasp until it's too late. For experienced day traders, 3x ETFs...
At higher magnification, mitochondria from OEX plants exhibited a simpler structure than those in Col-0 and KO plants. In general cristae were slightly less abundant in OEX plants (Figure 3B lower panel (black arrows)). The invaginations of the inner membrane were counted on 10 mitochondrial ...
There are three sliders at the bottom of Lens Corrections panel: Distortion, Chromatic Aberration and Vignetting. The default setting for each is 100, and you may adjust the sliders to vary the strength of the corrections. For instance, with this particular photo, I felt that Lightroo...
This is usually OK for color work, but unacceptable for black-and-white. If there is too much NR, we say that the image looks "like a cartoon," because it has sharp edges, but just flat color in between those edges. If you printed the entire image at the same magnification as the ...
Having a secondary mirror in the light path does have a negative impact on the performance of the scope and things like Strehl ratio. That's one reason why reflectors which are highly regarded for planetary observing and which deliver fantastic contrast and detail for their aperture tend to be...
Christopher Polk, Getty Images 18. Metallica As the biggest metal band in the world, your work is put under a microscope with every move dissected. Metallica have worked well under this magnification, giving their fans some of the most unique experiences in the world with loads of special and...
What I have said is that these conversations about which is better hardly ever include the contrast sensitivity threshold and resolution of the human eye. No matter how perfect the scope, the smaller it is, the dimmer the view is (for a given magnification based on the diminished exit pupil...
