Mathematically, the energy of a wave E is directly proportional to the square of its amplitude A. That is, E ∝ A².So, since a 6 foot wave as higher amplitude than a 3 foot wave, it thus has more energy.

Their direction of motion is north and west.

Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin.

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

The different types of waves have different uses and functions in our everyday lives. The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through.

While an accidental collision with a sperm whale at night accounted for sinking of the Union in 1807, the Essex incident some 30 years beforehand was the only other documented case of a whale deliberately attacking, holing, and sinking a ship.

Tour operators generally halt their propellers to remain at a distance from the whales, although the massive mammals then often swim up to the boats. The movement of the passengers likely wouldn’t have been enough to flip a boat of that size, said Staples.

Whales are susceptible to collisions with marine vessels, which may cause serious injury or death and can damage vessels. Mariners in Glacier Bay must be vigilant and may need to make active avoidance maneuvers to avoid close encounters with whales.

RMS Titanic: The original cruise ship disaster, the “unsinkable ship” struck an iceberg in the North Atlantic on its maiden voyage in 1912 and sank into the icy water, killing more than 1,500 of its 2,200 passengers and crew.

The Times notes that from 1980 to 2012, about 16 cruise ships have sunk. Typically, cruise ships that sink are those sailing in inhospitable waters, like the Antarctic Ocean, or ships belonging to smaller lines.

“The captain goes down with the ship” is a maritime tradition that a sea captain holds ultimate responsibility for both their ship and everyone embarked on it, and in an emergency will either save those on board or die trying. Smith, the tradition precedes Titanic by at least 11 years.

The ship’s security cameras frequently indicate evidence that man overboard situations are intentional. (If they do fall, it’s because they’ve climbed onto a railing or somewhere else they shouldn’t be.) Passengers either jump from their cabin balcony or from a high deck on the ship.

The cruise ships fill unsold cabins by simply changing the way of general sales. Many cruise liners now sell expensive inside cabins & term as a “free upgrade” to a Balcony cabin which is in fact a discounted price for a Balcony cabin.

Cruise ships have small jails onboard, they are called brigs. The jails are located in the crew only areas and guests rarely see them. The onboard jails are small and used as a place to hold guests suspected of breaking the law or those who are acting in a dangerous or reckless way.

Australian ferry builder Incat Tasmania’s world first high speed dual-fuel vehicle and passenger ferry is the world’s fastest ship having achieved a lightship speed of 58.1 knots – (107.6 kilometres an hour).

Titanic, in full Royal Mail Ship (RMS) Titanic, British luxury passenger liner that sank on April 14–15, 1912, during its maiden voyage, en route to New York City from Southampton, England, killing about 1,500 (see Researcher’s Note: Titanic) passengers and ship personnel.

Cruise ship codes “Operation Rising Star” means a passenger has passed away. Code Red – Outbreak of norovirus or illness. It means the ship must undergo deep cleaning and sick passengers should stay in their rooms. Code Green and Code Yellow indicate less severe problems.
