H E Edgerton, improved greatly on the stroboscope and this was made widely available by General Electric. Strobes had been invented more than a hundred years earlier in Belgium.
He then went on to improve sonar, by introducing the element of 'side-scan' sonar, with which many pictures of the ocean floor are made. These have much more resolution and display than 'ping' sonar.
What else can I help you with?
When you freeze water and it expands does it melt more water than before?
No. Under controlled circumstances, when you freeze 1 measure of water, it expands to about 1 and 1/10th of a measure. When melted, it will once again equal 1 measure of water.
When water goes from solid to liquid the distances between the three atoms within a molecule?
When water goes from solid to liquid, the distances between the hydrogen and oxygen atoms within a water molecule remain relatively constant. However, the intermolecular distances between water molecules increase as the solid structure breaks down into a more fluid arrangement.
What is NM the abbreviation for?
NM is the abbreviation for "nautical mile," which is a unit of measurement used in air and marine navigation. It is based on the circumference of the Earth and is commonly used to measure distances over water.
What instrument is used to measure water vapour in the atmosphere?
A hygrometer is used to measure water vapor in the atmosphere. This instrument can measure humidity levels in the air to determine the amount of water vapor present.
How would you measure a tub of water?
To measure a tub of water, you can use a measuring cup or a graduated cylinder to measure the volume of water in liters or milliliters. Alternatively, you can weigh the tub on a scale before and after filling it with water to determine the weight of the water in kilograms or pounds.
How far can gannets swim Under the water?
It is believed that they can dive to a depth of 50 feet to capture prey and will swim under water for short distances when pursuing their prey.
What can A sonar device that uses the echoes of the ultrasound underwater find?
A sonar device can detect objects underwater by emitting sound waves and analyzing the echoes that bounce back. It can be used to find underwater features such as fish, submarines, shipwrecks, or the seafloor.
What is echolcation?
It is an audio form of radar - the ability to tell the size and distance of object by listening to the echoes they produce. Bats use it in the air. Dolphins, porpoises and whales use it under water.
How do you measure the volume of a material?
Try Archimedes method: dip it under water (if possible) and see how much water overflows.
How do echoes help to provide information in a sonar?
because sound travels faster in water
How do you determine the volume of an irregularly shaped object that floats?
You can push it under water / under the liquid's surface, and measure the displacement of liquid.
Can a whale talk?
No. If a whale could talk that would be as weird as my sister. _______________________________________________________________________ Whales have been known to communicate great distances under water. Scientists are still trying to decipher what the sounds they make represent. _______________________________________________________________________ No. Whales can't talk in human language but can talk or communicate communicate great distances under water through high frequency sound waves just like dolphins.
What technology did scientists use in the mid 1900's to map the mid-ocean ridge?
they probably would use a sonar which is a device that bounces sound waves off under water objects and then records the echoes of these sound waves. =]
What uses sound waves to find things under water?
Sonar technology uses sound waves to find objects under water by sending out sound pulses and measuring the time it takes for the signals to bounce back. By analyzing the returning echoes, sonar systems can determine the distance, size, and shape of underwater objects.
What is a beacker and how is it used?
A beaker is basically a glass cup with numbers on the side.It is used to measure water with. You might use it to heat water under a Bunsen Burner.
Can currents carry water great distances?
YES, they can.
How do you measure volume of myself?
you need to fill a bath half full. then get into the bath and go under the water. the resultant height change in the water level will reflect you volume. I would suggest that you remain under the water for at least 10mins to allow the water surface level to stablise
