Morse+Code

__ Our Questions __

Beginning in 1836, [|Samuel F. B. Morse] and [|Alfred Vail] developed an [|electric telegraph], which sent pulses of electrical current to control an electromagnet that was located at the receiving end of the telegraph wire. The technology available at the time made it impossible to print characters in a readable form, so the inventors had to devise an alternate means of communication. In 1837, [|William Cooke] and [|Charles Wheatstone] began operating electric telegraphs in England that also had electromagnets in the receivers; however, their systems used needle pointers that rotated to indicate the alphabetic characters being sent. __Who invented Morse code?__ Samuel F B Morse and Alfred Vail. __When was Morse code invented?__ It was invented in 1836  __Where was Morse code invented?__ In the United States of America.  __What was Morse code (MC) used for?__ To send messages, for emergencies in the war, and to communicate.  __How did they use Morse code?__ A series of dots and dashes represent letters and numbers.  __When was Morse code used?__ In World War 1 and 2, and in emergencies.  __What machine did they use to make Morse code?__ The most common machine was called a “straight key.”  __Is Morse code still being used today?__ The most popular current use of Morse code is by [|amateur radio operators]. Morse code has been employed as an [|assistive technology], helping people with a variety of [|disabilities] to communicate. An important application is signalling for help through [|SOS], "**· · · — — — · · ·**". This can be sent many ways: keying a radio on and off, flashing a mirror, toggling a flashlight and similar methods. Military ships, including those of the [|U.S. Navy], have long used [|signal lamps] to exchange messages in Morse code. Modern use continues, in part, as a way to communicate while maintaining [|radio silence]. <span style="font-size: 14pt; font-family: 'Arial','sans-serif';"> __Who was the first person to use Morse code?__ <span style="font-family: 'Arial','sans-serif';">Charlie Babbage, Joseph Henry and Samuel Morse. <span style="font-size: 14pt; font-family: 'Arial','sans-serif';"> __How did others know Morse code was being sent?__ <span style="font-family: 'Arial','sans-serif';">It was received by amateur radio. <span style="font-size: 14pt; font-family: 'Arial','sans-serif';"> __How do we read Morse code?__ Here is a picture of the morse code alphabet. __<span style="font-size: 14pt; font-family: 'Arial','sans-serif';">What does Morse code sound like? __ media type="youtube" key="JJtJve1Aqu8" height="344" width="425" <span style="font-size: 14pt; font-family: 'Arial','sans-serif';"> __<span style="font-size: 14pt; font-family: 'Arial','sans-serif';">Why couldn’t they make computers instead? __ <span style="font-family: 'Arial','sans-serif'; mso-ansi-language: EN;">The technology available at the time made it impossible to print characters in a readable form, so the inventors had to devise an alternate means of communication. <span style="font-family: 'Arial','sans-serif';"> <span style="font-size: 14pt; font-family: 'Arial','sans-serif';"> __<span style="font-size: 14pt; font-family: 'Arial','sans-serif';">How do you send Morse code? __ <span style="font-size: 14pt; font-family: 'Arial','sans-serif';">You send it using dots and dashes over a telegraph wire.
