# Understanding Wave - Calculation Question

The SPM Physics Workbook is developed under the One-School.net Free Books Project. The content of this book is strictly follow Malaysia SPM (Sijil Pelajaran Malaysia) syllabus. The aim of this project is to provide a complete electronic supplementary network for students to develop self-learning skills by breaking the spoon-feed rituals and to encourage them to compile educational information from the Internet.

1. Figure above shows the pattern of wavefronts produced by bob dipper at a frequency of 25Hz in a ripple tank. Find the speed of the wave.
5m
0.05m
1.25m
0.3m

2. In a ripple tank experiment, waves are produced at the rate of 24 waves per second and the distance between 5 successive ripples is 20cm. The experiment is repeated by changing the frequency of the vibrator, and the new distance between 5 successive ripples is 12cm. What is the new frequency of the vibrator?
100Hz
60Hz
20Hz
40Hz

3. The end coil of a slinky spring is connected to a motor which is moving forward and backward at a frequency of 4Hz. Given that the distance between four successive rarefactions is 60cm. What is the speed of the speed of wave produced?
2.4 ms-1
0.8 ms-1
2.5 ms-1
1.0 ms-1

4. A sound wave of wavelength 4mm travels in air at a frequency of 6.0 × 104 Hz. Find the time take by the wave to travel 60m.
