Red light has a relatively long wavelength compared to other colors in the visible spectrum, making it highly visible even in adverse weather conditions or low light situations. This visibility ensures that drivers can easily recognize and respond to the signal, reducing the risk of accidents.

Red light has a longer wavelength and lower frequency compared to other colors in the visible spectrum, such as blue or violet light."

Cyclones, also known as hurricanes or typhoons depending on their location, are powerful tropical storms characterized by low-pressure centers, strong winds, and heavy rainfall. These storms form over warm ocean waters near the equator and typically occur in regions with sea surface temperatures of at least 26.5 degrees Celsius (79.7 degrees Fahrenheit).

The formation of a cyclone involves several key factors:

1. Warm Ocean Water: Cyclones require warm ocean water as a source of energy. Warm, moist air near the ocean's surface rises rapidly, creating an area of low pressure.
2. Coriolis Effect: As the warm, moist air rises, it begins to rotate due to the Coriolis effect, which is caused by the rotation of the Earth. In the Northern Hemisphere, cyclones rotate counterclockwise, while in the Southern Hemisphere, they rotate clockwise.
3. Convergence: The rotating air draws in more warm, moist air from the surrounding area, causing further convergence and upward motion. This process strengthens the low-pressure system at the center of the cyclone.
4. Vertical Development: As the warm, moist air continues to rise, it cools and condenses, forming towering cumulonimbus clouds and releasing heat into the atmosphere. This process of vertical development fuels the cyclone's intensification.
5. Eye Formation: In the center of the cyclone, a region of relatively calm and clear weather known as the eye may form. The eye is surrounded by the eyewall, where the strongest winds and heaviest rainfall occur.

Once formed, cyclones can persist and intensify as long as they remain over warm ocean waters and are not disrupted by factors such as wind shear or interaction with land. They may gradually weaken as they move over cooler waters or encounter unfavorable atmospheric conditions. Cyclones can cause widespread destruction and pose significant threats to coastal communities through storm surge, high winds, heavy rainfall, and flooding.
