Distinguish among amplitude, wavelength, frequency, and period.
To distinguish:
Among amplitude, wavelength, frequency, and period.
Answer to Problem 1RCQ
Solution:
Amplitude is maximum displacement of wave, wavelength is the distance between two parallel parts of wave, frequency is number of oscillations per second, and period is time taken to complete one oscillation.
Explanation of Solution
Amplitude of a wave is defined as maximum displacement from the equilibrium position of an object oscillating around such equilibrium position. Amplitude tells the amount of energy a wave is carrying.
Wavelength is the distance between adjacent identical parts of a wave, parallel to the direction of propagation. It is represented by
Frequency is defined as number of waves passing by a specific point per second. It is denoted by
Period is defined as the times taken by a wave to complete one single oscillation. It is measured in

- 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_forwardThe amplitude of a lightly damped oscillator decreases by 3.0% during each cycle.
