What distinguishes a wave from an oscillation?
Answer to Problem 1FTD
Explanation of Solution
A travelling disturbance that transports energy but not matter constitutes a wave. An oscillation is one which is a repetitive motion of matter.
When a body oscillate it moves in a repetitive fashion. The body itself moves and produces motion in the form of a wave. The body continues to be in motion to constitute the oscillation. In waves on the other hand, the body does not move. The wave in its motion transports the energy and not the matter.
In a wave motion the energy get transported whole way. The matter in the path oscillates in the locality and do not move with the wave. Thus oscillation of matter takes place as the wave propagates which is only localized and the energy in the medium moves with the wave.
Conclusion:
Thus, a wave is different from an oscillation in the fact that in the propagation of wave matter is not transported, only energy is.

- An automobile with a mass of 1000 kg, including passengers, settles 1.0 cm closer to the road for every additional 100 kg of passengers. It is driven with a constant horizontal component of speed 20 km/h over a washboard road with sinusoidal bumps. The amplitude and wavelength of the sine curve are 5.0 cm and 20 cm, respectively. The distance between the front and back wheels is 2.4 m. Find the amplitude of oscillation of the automobile, assuming it moves vertically as an undamped driven harmonic oscillator. Neglect the mass of the wheels and springs and assume that the wheels are always in contact with the road.arrow_forwardA cars 30.0-kg front tire is suspended by a spring with spring constant k = 1.00 105 N/m.

A spring, with a spring constant of 100 N/m is attached to the wall and to the block. A second block of 0.50 kg is placed on top of the first block. The 2.00-kg block is gently pulled to a position x=+A and released from rest. There is a coefficient of friction of 0.45 between the two blocks. (a) What is the period of the oscillations? (b) What is the largest amplitude of motion that will allow the blocks to oscillate without the 0.50-kg block sliding off?arrow_forward
- A small object is attached to the end of a string to form a simple pendulum. The period of its harmonic motion is measured for small angular displacements and three lengths. For lengths of 1.000 m, 0.750 m, and 0.500 m, total time intervals for 50 oscillations of 99.8 s, 86.6 s, and 71.1s are measured with a stopwatch. (a) Determine the period of motion for each length. (b) Determine the mean value of g obtained from these three independent measurements and compare it with the accepted value.
