Samuel Morse invented the telegraph and the code that the telegraph used (Morse code).

Morse code. Still used today in bad communication conditions.

The letter O is represented by dash dash dash

ohhhhhh you must be one of those people who have absoluteley no idea what so ever of what it is like being a teenager in the 21st century we do not have codes or words we use and no-one i know (except real idiots uses the word 'cool') there are no codes its just normal to us theres no codes its just normal to us not 'cool' or any other 1980's retro word just normal 1st you are prob a parent trying to figure out wat their kid says jst ask ur friends or kid then you'll know

Morse code was developed by a man named Samuel Morse. In 1844, the first message using this special code made of various sequences of dots and dashes or short and long signals was sent over a telegraph line between Baltimore and Washington.

In 1848, the code was adapted by a man named Friedrich Gerke and his version is the one that has become internationally accepted and used.

The Germans used the Enigma in WW2. It had a set of gears that when you pressed a letter on the keyboard, it seemed to randomly type another letter on the sheet of paper you were typing on. only if you had the same set of gears could you translate the code to English. The gears were interchangeable so you could create many different codes.

Morse code alphabet (in international Morse code) is:

A: .-

B: -...

C: -.-.

D: -..

E: .

F: ..-.

G: --.

H: ....

I: ..

J: .---

K: -.-

L: .-..

M: --

N: -.

O: ---

P: .--.

Q: --.-

R: .-.

S: ...

T: -

U: ..-

V: ...-

W: .--

X: -..-

Y: -.--

Z: --..

What hath God wrought - it's a phrase from the Bible

From one telegraph station to another - instantly. However telegraph stations were not very far apart so the message had to be retransmitted onwards. Originally this was done manually - an operator had to listen for incoming messages, write them down and then re-key tem. Later on they used punched tape which was produced when a message was received and could be automatically retransmitted. End to end - from the sender to the recipient could take several hours or days if overseas depending on the number of "hops".

If there is a light source reflecting your mirror at a certain angle it is possible to send a Morse code to another person from a distance.

Morse Code, invented in the 1830s, uses two symbols, the dot and the dash, in sequences, to indicate letters. In 1836, Samuel Morse demonstrated the ability of a telegraph system to transmit information over wires. The information was sent as a series of electrical signals. The most well-known usage of Morse code is for sending the distress signal: SOS. In the year 1999, Morse code is being replaced by a new satellite-based system for sending distress calls at sea.

It's a series of dots lines and spaces that when arranged in a certain order make out words.

Three dashes in Morse Code mean the letter O. 3 dots, followed by 3 dashes, followed by 3 dots is Morse Code for SOS.

Ambiguous question. (1)To call for help from other ships. (2)Morse code was the standard code used for radio communication from ships at the time.

Samuel FB Morse devised both the telegraph system and the code. the mode of code- that is dots and dashes was more or less discovered accidentally, the code itself was not. They used printing telegraphs which were clockwork tape registers ( this being the l840"s) and these were tied into the power supply so the shortest interval was a dot, a longer one, a dash. So, this being understood the Code was worked out. There are differences between the original Morse Code and the modern International Morse Code on some letters and punctuations. Somewhat oddly, one of the best-known Morse ciphers- the code for Red Alert: - - - - Four longs, evenly spaced- is not in the original land line (Morse) or international ( Radio-telegraph) forms of the Morse Code, but it well known. Four Longs- Red Alert! Even Spector used it in some of his songs.

Not generally. Morse code is used very little these days, except by the military and the Boy Scouts, or in some kind of emergency where no other form of communication is available. When Morse code was more prevalent, the device used to transmit the "dots and dashes" was known as a telegraph. A very simple electrical switch that tapped the current on and off to transmit via overland wires, and later, by radio.
