In the Morse code, which letter is indicated by 3 dots?

In Morse code, each letter is represented by a combination of dots and dashes. The letter S is indicated by three dots because the Morse code sequence for S is "...". The dots in Morse code represent short signals or "dots," while the dashes represent longer signals or "dashes." Therefore, in the case of three dots, it indicates the letter S in Morse code.
