What is the difference between ray theory and mode theory of light?
Wiki User
∙ 11y ago
mode theory assumes light to be a wave, but ray theory does not assume light to be either a wave or particle. ray theory is used to calculate properties like magnification or distance to the object or image in an optical system, where as mode theory is used find bandwidth, reflection coefficients and parallel polarization.

Explain the propagation of light through optical fiber and appilication of optical fiber as wave guide and sensor?
The concept of light propagation, the transmission of light along an optical fiber, can be described by two theories. According to the first theory, light is described as a simple ray. This theory is the ray theory, or geometrical optics, approach. The advantage of the ray approach is that you get a clearer picture of the propagation of light along a fiber. The ray theory is used to approximate the light acceptance and guiding properties of optical fibers. According to the second theory, light is described as an electromagnetic wave. This theory is the mode theory, or wave representation, approach. The mode theory describes the behavior of light within an optical fiber. The mode theory is useful in describing the optical fiber properties of absorption, attenuation, and dispersion
What is the difference between a p90 and a f90?
well, i dont really know about this although i have p90.... but i think p90 is the usual mode of p90, but if it is p90, it use silencer
Explain the difference between acceleration and deceleration?
When an object is moving with different velocity with respect to time then the object is in acceleration or decceleration mode. If the rate of change of velocity is positive then it is said to be accelerated, if its negative it is said to be deaccelerated.
What is a light gate?
Light gates are simple optical circuits that have an opening between an emitter and receiver. If the path between the two is interrupted, a signal is sent to a computer or other data recorder. Some gates work in continuous mode, meaning the signal is different when the light is blocked, for example high or low voltage. Others work in pulsed mode, which responds by giving a pulse whenever the 'state' of on or off changes. And a third kind send a signal continuously while the path is open, and simply stop the signal when the path is broken. These gates are typically used for timing and detection. Many automatic garage doors use a light gate to detect whether the door will come down on something (or someone!).
