Light has several key characteristics that define its behavior and properties. These characteristics include: 1. **Wavelength and Frequency**: Light can be described in terms of its wavelength (the distance between consecutive peaks of a wave) and frequency (the number of waves that pass a point in a given amount of time). The wavelength is inversely related to frequency, and together they determine the color of visible light.
Light dues are charges levied on ships using certain ports and waterways to help fund the maintenance and operation of navigational aids, such as lighthouses, buoys, and other signaling systems that assist in marine navigation. These dues are typically paid based on the size, type, and tonnage of the vessel and are used to ensure the safety and efficiency of maritime traffic.

The term "lubber line" refers to a distinctive line or mark on a ship's compass or binnacle that's used as a reference point for navigation. It indicates the direction that the ship's bow is pointing relative to the vessel's heading. The lubber line helps sailors align their compass heading with the direction of the ship. When navigating, it is crucial to know the correct heading, especially when making turns or adjustments to maintain a desired course.
Magnetic deviation, also known as compass deviation, is the error in a magnetic compass reading caused by local magnetic fields interfering with the Earth's magnetic field. This deviation occurs when there are ferromagnetic materials or electromagnetic fields nearby, which can distort the compass needle's alignment with the Earth's magnetic field. Deviation can happen due to various factors, including: 1. **Metal Structures**: Large metal objects, such as ships' hulls or buildings, can create magnetic fields that affect compass readings.
