Concept explainers

A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).

Quality Of Sound

A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vib…

Categories of Sound Wave

People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules th…

BIO The Love Song of the Midshipman Fish When the plainfin midshipman fish (Porichthys notatus) migrates from deep Pacific waters to the west coast of North America each summer, the males begin to sing their “love song,” which some describe as sounding like a low-pitched motorboat. Houseboat residents and shore dwellers are kept awake for nights on end by the amorous fish. The love song consists of a single note, the second A flat below middle C. (a) If the speed of sound in seawater is 1531 m/s, what is the wavelength of the midshipman’s song? (b) What is the wavelength of the sound after it emerges into the air? (Information on the musical scale is given in Table 14-3.)

2.62 Collision. The engineer of a passenger train traveling at 25.0 m/s sights a freight train whose caboose is 200 m ahead on the same track (Fig. P2.62). The freight train is traveling at 15.0 m/s in the same direction as the passenger train. The engineer of the passenger train immediately applies the brakes, causing a constant acceleration of 0.100 m/s² in a direction opposite to the train's velocity, while the freight train continues with constant speed. Take x = 0 at the location of the front of the passenger train when the engineer applies the brakes. (a) Will the cows nearby witness a collision? (b) If so, where will it take place? (c) On a single graph, sketch the positions of the front of the pas- senger train and the back of the freight train.

2.70 Egg Drop. You are on the Figure P2.70 roof of the physics building, 46.0 m above the ground (Fig. P2.70). Your physics professor, who is 1.80 m tall, is walking alongside the building at a constant speed of 1.20 m/s. If you wish to drop an egg on your profes- sor's head, where should the profes- sor be when you release the egg? Assume that the egg is in free fall. 2.71 CALC The acceleration of a particle is given by ax(t) = -2.00 m/s² +(3.00 m/s³)t. (a) Find the initial velocity Vox such that v = 1.20 m/s 1.80 m 46.0 m
