Morse code is a method used in telecommunication to encode text characters as sequences of two different signal durations, called dots and dashes or dits and dahs. It was developed by Samuel Morse and Alfred Vail in the early 1830s for use with the telegraph. Morse code has been widely used historically in radio communication, aviation, and maritime communication, although it has largely been replaced by digital communication methods in recent years.
Morse Code Chart:
Here's a chart showing Morse code representations for each letter of the alphabet:
- 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: --..
Numbers:
- 1: .----
- 2: ..---
- 3: ...--
- 4: ....-
- 5: .....
- 6: -....
- 7: --...
- 8: ---..
- 9: ----.
- 0: -----
Punctuation and Special Characters:
- Period (Full Stop): .-.-.-
- Comma: --..--
- Question Mark: ..--..
- Apostrophe: .----.
- Exclamation Mark: -.-.--
Prosigns:
Prosigns are special Morse code sequences used for specific purposes in radiotelegraphy, such as to signify the end of a message or to indicate distress.
- End of Work: .-.-.
- Starting Signal: -.-.-
Morse Code Transmission:
In Morse code, each character is represented by a unique sequence of dots and dashes. The duration of a dash is typically three times longer than that of a dot. The space between letters within a word is one dot, while the space between words is typically three dots.
For example, the word "HELLO" would be transmitted as:
- .... . .-.. .-.. ---
And "WORLD" would be transmitted as:
- .-- --- .-. .-.. -..
Learning Morse code involves memorizing these sequences for each letter, number, and special character, as well as practicing the transmission and reception of Morse code messages.
