What is Morse Code ?
Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment.
- Length of a dot is 1 unit.
- Length of a dash is 3 units.
- The space between parts of the letter is 1 unit.
- The space between different letters is 3 units.
- The space between different words is 7 units.
Example :
Hi this is Nikhil
.... .. / - .... .. ... / .. ... / -. .. -.- .... .. .-..
- A lighthouse is a structure from which light is projected at night, or which serves as a marker by day, to guide ships sailing in coastal waters.
- Every lighthouse emits a distinctive series of flashes known as its characteristic. These flash sequences allow ship captains to time intervals between flashes so that they can identify lighthouses.
- In areas with narrow bays or ports, lighthouses use red and green lights to distinguish the side of the entrance. In navigation, red lights are associates with the port side, or left side, and green is associated with the right. Upon entering a port, the ship will see the red light on the left.
- Occasionally, lighthouses will use red light to notify incoming ships of danger. They will use a flashing red light or switch between red and white to distinguish the warning from their normal characteristics. Red traditionally means stop, and informs the ship to seek out further information.
- In areas where the port is surrounded by many buildings, lighthouses use colored light to distinguish themselves from the surrounding white lights. At night, it is difficult to differentiate between multiple white lights, so lighthouses use their characteristics for easier navigation.
- Morse code shows short and long flashes that represent dots and dashes, respectively. These dots and dashes are grouped to represent code characters.
- Lighthouse keepers used to communicate with ships by flashing a light and using Morse Code.
- Modern satellite-based navigational systems that can be installed on ships of all sizes have replaced the lighthouse as a primary navigational aid.
