Phenomena of Wave 2  Difraction and Interference The SPM Physics Workbook is developed under the OneSchool.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 selflearning skills by breaking the spoonfeed rituals and to encourage them to compile educational information from the Internet.

11. Two round dippers separated by a distance of 6.0 cm is connected to a vibrator to produce two coherent sources of spherical waves. The distance between the sources and where x is measured is 20.0 cm. If the distance between two successive antinode lines is 3.0 cm, determine the wavelength for the spherical wave.
Magnetic Field
A magnetic field is a region in the surrounding of a magnet which a magnetic material experiences a detectable force.
