steradian वाक्य

उदाहरण वाक्य

1. A steradian can be defined as "'the solid angle subtended at the center of a unit sphere by a unit area on its surface " '.
2. This gives the expected results of 4 steradians for the 3D sphere bounded by a surface of area and 2 radians for the 2D circle bounded by a circumference of length.
3. Compiling Kikuchi maps which cover more than a steradian requires that one take many images at tilts changed only incrementally ( e . g . by 2?in each direction ).
4. Based on the fact that 1 candela = 1 lumen?" steradian and 1 lumen = 1 / 683 Watts, 1 candela should be 1 / 683 Watt?" steradian.
5. Based on the fact that 1 candela = 1 lumen?" steradian and 1 lumen = 1 / 683 Watts, 1 candela should be 1 / 683 Watt?" steradian.
6. If the source emitted uniformly in all directions, the total radiant flux would be about 18.40 mW, since there are 4 & pi; steradians in a sphere.
7. Those molecules together generate a Raman signal in the order of 2?0  " 11 W ( 20 pW ) or roughly one hundred million photons / sec ( over 4? steradians ).
8. The solid angle of a face subtended from the center of a platonic solid is equal to the solid angle of a full sphere ( 4 steradians ) divided by the number of faces.
9. Because the surface area " A " of a sphere is 4 " r " 2, the definition implies that a sphere measures 4 ( H " 12.56637 ) steradians.
10. A careful distinction needs to be made between dimensionless derived units, such as the radian ( rad ) and steradian ( sr ) which are useful for clarity, although they are both algebraically equal to 1.
