Distance (D), Width (W), Throw Ratio (R) If the distance and width are known, calculate the throw ratio using the formula: R = D / W [1] If the screen width and throw ratio are known, calculate the distance using the equivalent formula: D = W x R. Although it is often stated as a single value (or range of values), throw ratio is a comparison of ...

A scene will be properly illuminated for every combination of f‑stop and distance shown on this flash device's exposure calculation dial, each of which equals the same guide number. The guide number here (full power setting, ISO 100, and normal-angle coverage) is 37 for calculations made in meters (yellow arrow) and 120 for feet (orange).
This critical object distance "h" is known as the Hyperfocal Distance. For a camera focused on this distance, D 1 = ∞ and D 2 = h/2, and we see that the range of distances acceptably in focus will run from just half the hyperfocal distance to infinity. The hyperfocal distance is, therefore, the most desirable distance on which to pre-set the ...
The range, R, is the greatest distance the object travels along the x-axis in the I sector. The initial velocity, v i, is the speed at which said object is launched from the point of origin. The initial angle, θ i, is the angle at which said object is released.
d is the total horizontal distance travelled by the projectile. v is the velocity at which the projectile is launched g is the gravitational acceleration —usually taken to be 9.81 m/s 2 (32 f/s 2 ) near the Earth's surface
The top mark is at 1.500 m and the lower is at 1.345 m. The difference between the rod readings is 0.155 m, yielding a distance to the rod of 15.5 m. A typical surveyor's instrument reticle has two pairs of stadia marks. One pair are on the horizontal centreline and the other on the vertical cross hair.
The Minkowski distance can also be viewed as a multiple of the power mean of the component-wise differences between and . The following figure shows unit circles (the level set of the distance function where all points are at the unit distance from the center) with various values of p {\displaystyle p} :
