WebAug 11, 2024 · 14.4: Optical Theorem. because P l ( 0) = 1 . This result is known as the optical theorem , and is a consequence of the fact that the very existence of scattering requires scattering in the forward ( θ = 0) direction, in order to interfere with the incident wave, and thereby reduce the probability current in that direction. WebOptical microscopes can be simple, consisting of a single lens, or compound, consisting of several optical components in line. The hand magnifying glass can magnify about 3 to 20×.
