WebNumerical Aperture (NA) = η • sin (α) (1) where α equals one-half of the objective's opening angle and η is the refractive index of the immersion medium used between the objective and the cover slip protecting the specimen (η = 1 for air; η = 1.51 for oil or glass). By examining Equation (1), it is apparent that the refractive index is ...

So hopefully this will explain to you-a line is a line that goes on forever in both directions. A line segment is something that has a start and an end (2 endpoints)-so basically the opposite of a line. Then a ray is something with a starting point, but no end. So a ray is like a line, but only one part is endless.

WebWave Fronts and Rays. In the graphic representation and analysis of wave behavior, two concepts are widely used—wave fronts and rays. A wave front is a line representing all … WebA wavefront is an imaginary surface representing corresponding points of a wave that vibrate in unison. A wavefront is the set of all locations in a medium where the wave is at the same phase. This could be where all the crests are, where all the troughs are, or any phase in between. Wavefronts are useful for showing how waves move in 2 dimensions.
