Concept explainers
You dip your finger repeatedly into a puddle of water and make waves. What happens to the wavelength if you dip your finger more frequently?
Wavelength observed by the person when he dips a finger more frequently into the puddle of water.
Answer to Problem 34A
When a person dips his finger into the water more frequently, then wavelength of the water waves decreases.
Explanation of Solution
Introduction: Frequency
When a person dips his finger into the water, then water waves are produced concentrically. If the frequency of dipping into the water increases then more water waves will produce. Since frequency of a disturbance is inversely proportional to the wavelength. Thus, as the frequency increases, so will the wavelength decreases.
Conclusion: Thus, when a person dips his finger into the water more frequently, then wavelength of the water waves decreases.
