To detect, track, and sometimes identify objects via the emission of radio waves. Speed radar (like those used by police) can detect nearby objects and calculate their speed. Weather radar can detect the location of clouds and rain. Air traffic radar can detect and track unidentified flying objects. With the help a monopulse secondary surveillance radar, the radar system can identify the individual planes. Higher technology radars can detect and identify distant small objects with great precision.
I've been trying to find a satisfactory answer to this through a casual search on the web and nothing jumps out at me immediately which amazes me!What idiot sitting on some "standards committee" somewhere thought that brown would be a good colour for a live wire?For starters brown is the colour of earth, so anyone knowing nothing about electricity would assume that brown is earth and that live must be that fancy coloured green and yellow wire with fatal consequences no doubt.Nature gives us natural warning and danger colours and they are typically vivid colours or unnatural contrasts - such as green and yellow in snakes! Red is also a classic danger colour and means "stop" on traffic lights etc. So...why is the live wire not red ?From my dim and distant past I can vaguely recall messing around with plugs and wires and in those days I remember the live wire in the UK as being red. So...what caused the change? I suspect some crazy dictate from faceless bureaucrats at the so called European Union lol.The only reason I can think of for this madness is that major circuits which feed directly into the mains, tend to have live as red and neutral as black (earth is green or green and yellow I think). As a means of distinguishing between the two, brown was chosen as a "shade" of red to mean live - though why not choose vivid orange? Why do we need to distinguish between the two types of circuits anyway?Unfortunately, I suspect that the real answer lies in some legal case where an idiot was working in building somewhere and mixed up the old style red live of a lighting circuit with a red live straight from the mains and frizzled themselves to death. The family sued because they were short of cash and the legal precendent was set that wiring should be re-labeled in colour (because - displaying warning signs near every electrical outlet was deemed unpractical...doh!)CommentI think you're probably correct in assuming that it was dreamt up by some idiot in the European Union of Socialist Republics!

Reverend Sykes' voice seems distant to Scout after the decision because she is lost in her own thoughts and emotions. She is grappling with the implications of the trial and the injustice she witnessed, causing her to be mentally preoccupied and distant from what is happening around her.

A designated survivor is a member of the United States Cabinet who needs to be in a distant and undisclosed location when the President and other top leaders are gathered in a single location together.
It's evidence for what you meant to say but didn't ... that the speed of light isindependent of frequency.
the distance between the crests of two succesive waves is called the wavelength. It is directly related to the frequency of the wave
Words used to describe a relative location are adjectives or adverbs. The word relative is an adjective that describes the noun location.a near relative location (adverb)an very relative location (adverb)a popular relative location (adjective)a distant relative location (adjective)
This is used by some bats, cetaceans, and as sonar by submarines. A short acoustic ping is sent out, and then we listen for its reflection from a distant object. The velocity of sound in air is around 330m/s. The bats actually send out a ping of falling frequency; so that a high frequency return pulse indicates a close object; and a low frequency return pulse, a more distant object. When an object is close, a bat increases its ping rate. Some insects have developed avoidance behaviour to ultrasonic pings!
Type your answer here... A method of detecting distant objects and determining their position,velocity or other characteristics by analysis of very high frequency radio waves from their surface.
