What Makes Morse Code So Special?
Morse code is a clever way to turn each letter and number into a series of dots (short signals) and dashes (long signals). For example, the letter “E” is just one dot (.), and “T” is one dash (–). You can tap it, beep it, flash it with lights, or even knock on a wall. Morse code doesn't need the internet—just a little creativity!
Who Invented Morse Code and Why?
In the 1830s, a curious American named Samuel Morse wanted to find a faster way to send messages. With the help of his friend Alfred Vail, they created the Morse code system to work with the electric telegraph. Instead of waiting for letters in the mail, people could send words over wires as quick as a flash! That’s why Morse code is called the world’s first digital language.

FAQs on Complete Guide to Morse Code: Meaning, Usage & Exam Relevance
1. What is Morse code?
Morse code is a communication system that uses sequences of dots (•) and dashes (–) to represent letters, numbers, and punctuation.
- It was invented by Samuel Morse in the 1830s for the electric telegraph.
- Each letter or numeral has a unique combination of dots and dashes.
- Morse code is used in telecommunication, emergency signals like SOS, and by radio operators.
- It helped revolutionize long-distance communication and remains part of CBSE/UPSC General Knowledge syllabus.
2. How do you write SOS in Morse code?
The universal distress signal SOS is written in Morse code as ... --- ....
- S = ... (three dots)
- O = --- (three dashes)
- S = ... (three dots)
- Together: ... --- ...
- This pattern is recognized worldwide for emergencies and is exam-relevant for communication systems.
3. Who invented Morse code and when?
Morse code was invented by Samuel Morse and his assistant Alfred Vail in the 1830s.
