Phenomena of Wave - Reflection and Refraction
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.

5. Figure above shows a refraction of ripples in a ripple tank. If the speed of the ripples in region A is 0.1m/s, what is the speed of the ripples in region B?
Choose the best answer.
6. A water wave moves from a shallow region to a deep region with a velocity of 25 cm s-1 and 30 cms-1 respectively. What is the ratio of the wavelength in the shallow region to the wavelength in the deep region?
Choose the best answer.
7. A vibrator produces plane water waves that travel at a velocity of 20 cms-l. When the waves enter a shallower region, the wavelength becomes 1.6 cm and the speed of the wave become 16 cms-l. Determine the wavelength of the wave at the deeper region
Magnetic Field
A magnetic field is a region in the surrounding of a magnet which a magnetic material experiences a detectable force.
