waves help to not only propel the boat downwind but they also help to tell you where the wind is coming from.
sound waves
He absolutely did. There had to be a storm or two while he was sailing which caused waves. Anyway, I have NEVER heard of any ocean to be wave-less.
Waves that rely on a medium may not travel through space. These would include longitudinal waves, shear waves, and sound waves.
The prow of the sailing ship sliced cleanly through the waves.
They were thousands of miles from Britain and it took several months of sailing to reach the colonies from Britain.
I'm not sure about sailing, but fear of water and wave-like motions are technically termed: Water- Hydrophobia. Waves or wave like motions- Cymophobia or Kymophobia. Theses fears probably cause a fear of sailing. Hope this helped :S
A reach refers to sailing with the wind direction ranging from slightly ahead of the beam to almost direct abaft the direction of travel. A following sea means the waves are coming from behind the boat. This is a typical point of sail for long range sailing and trade winds traders.
frequency?diffusion?refraction?reflection? QDA SUCKS!
Electromagnetic waves, such as light, radio waves, and X-rays, do not require a medium to travel. These waves are able to propagate through a vacuum. In contrast, mechanical waves, like sound waves, do require a medium, as they rely on the vibration and movement of particles in a substance to transmit energy.
You can use them with fishing or when your sailing. it will push your boat/fish round. Also, waves can be used to generate energy. This is a sustainable way to get energy, and is simply known as Wave Energy, or Wave Power.
Yes. Electromagnetic waves, like light, can travel through a vacuum, they need no medium in order to be transmitted. Unlike sound waves, which are compression waves what rely on matter in order to be transmitted.
To study earth's interior, geologist often rely on indirect methods such as evidence from seismic waves, not fossils.
