In Morse code, “blink” is represented by a sequence of short and long pulses, known as “dits” and “dahs.” A dit is a short pulse, while a dah is three times longer. The Morse code representation for “blink” is “-…-,” where the hyphen (-) represents a dit and the dot (.) represents a dah. This sequence corresponds to the following pattern: short pulse, long pulse, short pulse, long pulse, short pulse.
