What is the standard length of a dot in Morse code for timing?

• A. One second
• B. One-fifth of a second
• C. Two seconds
• D. Three seconds

Answer: (B)

In Morse code, the standard length of a dot serves as the fundamental unit of timing for the transmission of signals. The duration of a dot is established as one-fifth of a second, which provides a consistent and manageable basis for understanding the relationship between various elements of Morse code. The timing in Morse code is structured around this basic unit. A dash in Morse code lasts for three times the duration of a dot, while the spaces between elements (intra-character spaces) and the spaces between letters and words are determined relative to the dot's length as well. By using one-fifth of a second for a dot, Morse code remains efficient for both human operators and automated systems, ensuring clarity and reducing the likelihood of error during transmission. This is why the choice of one-fifth of a second for the length of a dot is the correct answer.
