What visual distress signal is acceptable for night use only?
The acceptable visual distress signal for night use only is the pyrotechnic signal, such as flares or aerial rockets. These devices are designed to produce bright light or a significant display to attract attention during nighttime. It's important to ensure they are used in accordance with local regulations and safety guidelines.
Why we need high power to generate AM signal and low power to generate FM signal?
The reason FM has lower power and AM has higher power is because the more power that an AM signal has, the farther it will go, but FM does not work that way. AM waves can bounce off of the atmosphere, especially at night. This is the reason that you can hear AM stations from far away at night. FM, on the other hand, can't bounce. FM waves only go in a straight line from the tower and no matter how much power you transmit with, an FM wave will only go a short distance. AM Waves can travel through trees and buildings, and FM can't.
Why phosphor screen is used in night vision goggles?
In a night vision tube, the object of the tube is to convert incoming light particles (photons) to electrons. The electrons are then multiplied many times by the microchannel plate inside the tube. It is these multiplied electrons that are the output 'signal'. However, since your eye cannot see electrons, they are converted back to visible light by way of the phosphor screen which 'lights up' when energized by the electrons.
Who inverted the first traffic light?
The light was proposed by John Peake Knight, a railroad engineer. He modeled the traffic control after the system used by the British railroad. An arm was moved up or down by policeman to signal whether traffic should stop or go. The arms could not be seen at night so the signal was changed to using red and green gas lamps.

Does Brian keep the signal fire burning day and night?
No, Brian does not keep the signal fire burning day and night. He only maintains it during the day, as the fire would be riskier to manage during the night without proper supervision.
How did slaves remain undetected when escaping onto the underground railroad?
The 'Underground Railroad' network remained undetected because of its stealth techniques by resting by day, and traveling by night.
How did harriet Tubman help in the underground railroad?

Why was the underground railroad fast?
the underground railroad is not actually a railroad, but a escape system back in the 1800's to help slaves escape. it was not fast, and it could sometimes take the slaves months to get to the north. they were after all, hiding in houses and traveling at night. (so don't try to see if you can get a ticket on the underground railroad!)
Who were the conductor of the undergroud railroad?
the "conductors" was a code the system used to keep the underground railroad a secret. the "conductors were guides for the slaves who would go in and take the slaves out if they asked. the "conductors" would the travel at night on foot with the slaves for 10-12 hours at night, everyday.
What was a candle used for during the underground railroad?
During the Underground Railroad, candles served as a crucial source of light for escaping enslaved individuals and their allies while navigating dark spaces and hidden routes at night. They provided discreet illumination to avoid detection by patrollers and slave catchers. Additionally, candles were used to signal safe houses or locations, allowing fugitives to find refuge along their journey to freedom.
