It seems like no matter how far away from the ocean you are, you can still hold a seashell up to your ear and hear the roar of the waves rolling onto the shore. The best shells for producing this sound are the large, spiral conch shells. Some people have suggested that the sound you...
When we visualize waves, we often think of transverse waves — like the rolling waves on a beach — where the motion of the wave is perpendicular to the direction of energy transfer. However, sound waves are a different type altogether — a longitudinal wave. In longitudinal sound waves, suc...
Waves like this are called transverse waves. That just means the water vibrates at right angles to the direction in which the wave travels. Sound waves work in a completely different way. As a sound wave moves forward, it makes the air bunch together in some places and spread out in ...
what is sound? learn more {{tabitem?.headline?.t_id}} what is sound? sound is the vibration of particles in a medium like air that our ears perceive. it's created when something vibrates, producing sound waves that travel to our ears and are interpreted by our brains. sound plays a...
aYet the waves, no matter how big or how violent, affect only the surface of the sea. During most raging storms, the water a hundred fathoms (600 feet) beneath the surface is just as calm as on a day without a breath of wind. 正在翻译,请等待... ...
aThe size of a wave depends on how strong the wind is, how long it blows, and how large the body of water is. In a small bay big waves will never build up. But at sea the wind can build up giant, powerful waves. 波浪的大小依赖于怎样强风是,它多久吹,并且多么大水体是。 在一个小...
Like windows, doors are notorious for letting sound waves leak in and out. To create a better sound barrier around doors, swap hollow core doors for MDF (medium density fiber) or solid wood doors, and add closed cell foam tape or weather stripping around door jambs. If you have sliding ...
In physics, a wave is a disturbance that travels through a medium such as air or water, and moves energy from one place to another. Sound waves, as the name implies, bear a form of energy that our biological sensory equipment -- i.e., our ears and brains
If they are twice as far away, do you think the sound is half as loud? In fact, the intensity varies like the square of the distance. So, if you are twice as far away from the sound, the intensity is one-fourth of the previous intensity. Finally, does sound travel faster or ...
Since local fishermen discovered thresher sharks breaching the waves like dolphins above a sunken island called Monad Shoal more than 20 years ago, Malapascua has become a diving hotspot. Those who head underwater enjoy the perfect cocktail of rainbow-coloured coral gardens, almost-guaranteed...
