Concept explainers

Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.

Question

A sonar device emits waves of frequency 40 kHz. The wavelength of the wave in water is 0.032 m. Suppose that
the device is fixed to the bottom of the ship. It emits a signal and the echo from the ocean bed returns 0.8 second
later. What is the depth of the ocean at that point?

(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)
A man drops a rock into a well. (a) The man hears the sound of the splash 2.40 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? (b) What If? If the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated?
A bat flying at 5.05 m/s is chasing an insect flying in the same direction. The bat emits a 39.8-kHz chirp and receives back an echo at 40.6 kHz. (Take the speed of sound in air to be v = 343 m/s.) (a) What is the speed of the insect? m/s(b) Will the bat be able to catch the insect? Yes No Explain.

A deep sea ocean vessel uses SONAR to detect the ocean's bottom. Sound waves are emitted from the surface of the ocean and travel through the water at 1450 m/s. The ocean bottom is 1630 m below the surface. Determine the amount of time that passes before the sound waves are reflected back to the surface.
On December 26, 2004, a great earthquake occurredoff the coast of Sumatra and triggered immense waves (tsunami) thatkilled more than 200,000 people. Satellites observing these waves fromspace measured 800 km from one wave crest to the next and a periodbetween waves of 1.0 hour. What was the speed of these waves in m>sand in km/h? Does your answer help you understand why the wavescaused such devastation?
This is possibly a different atmosphere from ours. In any case, the speed of sound is computer-generated, and is 454 m/s this time. Light travels for us instantaneously. You see a lightning flash, and 7.6 seconds later, you hear the thunderbolt. How far away was the lightning (in meters)?
A stone is dropped down a well with a velocity of 3.28 ft/s and 16.30 seconds later the sound of the splash is heard. If the velocity of sound is 1130 feet per seconds. What is the depth of the well?
An average eardrum has an area of about 5.0x10-5m2. What is the force in Newton's exered on an eardrum if you are at the bottom of a water filled pool that is 2.39 meters deep? Use g=9.8 m/s2 and assume 3 figures in your answer.
