When launched, Hubble carried five scientific instruments: the Wide Field and Planetary Camera (WF/PC), Goddard High Resolution Spectrograph (GHRS), High Speed Photometer (HSP), Faint Object Camera (FOC) and the Faint Object Spectrograph (FOS). WF/PC was a high-resolution imaging device prima...
The reference path (26) can be changed in precise steps so that is has an equivalent length approximately equal to the path length of the light pulse component that is reflected from the object. The resulting small difference in path lengths can be precisely determined by directing the light ...
One’s body is the most important object in one’s life, serving as the essential medium through which one experiences the world and interacts with others and with one’s environment. Perceiving what constitutes this body (i.e., which objects are parts of one’s body and which are not) ...
An object emits light at a frequency of 230 GHz. If the object is moving toward you at two-fifths the speed of light, then what frequency of light will you observe coming from the object? In which material does light travel fastest? Light travel at a speed of 2.998\t...
Here is a sketch of the HUD. The LCD display emits light. That light is reflected by the 2 mirrors forming the HUD, then reflected by the windshield and finally enters the driver’s eyes. The driver sees a virtual image on the road giving him indications like for example here the sp...
