| 例句 | When researchers shine an x-ray beam through a sample, variations in the material will delay the wave front of the coherent x-rays to different degrees, creating a mottled intensity pattern on a distant detector. Rebirth of leading European facility promises revolutionary advances in x-ray science 2020-07-15T04:00:00Z “It's wave front stuff; this is the edge of science,” said Andrew Ellington, a biochemist at the University of Texas at Austin who was not involved in the research. Cells with lab-made DNA produce a new kind of protein, a ‘holy grail’ for synthetic biology 2017-11-29T05:00:00Z Instead, the scientists used the computer to run the radio waves backward in time from the screen to the distance where wave fronts hit the object. Stray Wi-Fi signals could let spies see inside closed rooms 2017-04-28T04:00:00Z If you send light produced in this way through a dispersive medium, Einstein predicted, the wave fronts should be deflected if the emission process were classical. Newly Published Einstein Writings Show the Prehistory of His Debates with Niels Bohr [Guest Blog] 2013-02-21T17:45:00.450Z As it traveled towards land, ocean ridges and undersea mountains pushed the wave fronts together, keeping the tsunami stable even as it hurtled towards the coast.

Brood of the Dark Moon The particles were thrown out on the wave front of the explosion, and they split further, spontaneously. The Leech In contrast, those reflected by the object are modified by it, and so some parts of the wave front arrive at the plate earlier and others later, depending on where they bounced off the object. Stray Wi-Fi signals could let spies see inside closed rooms 2017-04-28T04:00:00Z So that any section of a spherical wave front will always be at right angles to the ray of light. Aether and Gravitation Because as each wave front moves from air to water, it slows down. Islands of Space If we can send out a spherical wave front, and have it lengthen rapidly as it proceeds, we will have a wave front that is, at all points, different. Invaders from the Infinite It states that all points of a wave front of light in a vacuum may be regarded as new sources of wavelets that expand in every direction at a rate depending on their velocities. Our Legal Heritage : 600-1776 King Aethelbert - King George III What this apparatus, or ray screen, consists of, is a machine generating a spherical wave front of the nature of a molecular wave, but of just too great a frequency to do anything.
