We can always form the next number in the pattern by multiplying by 1.4, which is the square root of 2 as a rounded off decimal value. and so on. In the f-numbers we have a sequence of numbers, where we always multiply by a common value of 1.4 to generate the next number.

Fractional shortening (FS) for estimating systolic function Fractional shortening (FS) is calculated by measuring the percentage change in left ventricular diameter during systole. It is measured in parasternal long axis view (PLAX) using M-mode.

In very simple language, f-stop is the number that your camera shows you when you change the size of the lens aperture. You might have seen this in your camera before. On your camera's LCD screen or viewfinder, the f-stop looks like this: f/2.8, f/4, f/5.6, f/8, f/11, and so on.

F-stop (aka f-number) is the number that you see on your camera or lens as you adjust the size of your aperture. Since f-stops are fractions, an aperture of f/2 is much larger than an aperture of f/16.

An f-stop is a camera setting that specifies the aperture of the lens on a particular photograph. It is represented using f-numbers. The letter “f” stands for focal length of the lens.

Aperture (f/stop) is the size of the opening inside your lens through which light passes. ... The "f-stop" is the ratio of the focal length and the aperture diameter: f-stop = focal length / aperture diameter. The aperture, in combination with shutter speed, determines how much total light that reaches the sensor.

Since the circuit is at resonance, the impedance is equal to the resistor. Then, the peak current is calculated by the voltage divided by the resistance. The resonant frequency is found from Equation 15.6. 5: f0=12π√1LC=12π√1(3.00×10−3H)(8.00×10−4F)=1.03×102Hz.
