Physics for SPM: Refraction of Waves
http://physicsf45spm.blogspot.com/2012/03/refraction-of-water-waves.html
O-Level and IGCSE Yrs 10/11 students. (Published By: Tan of PJ, Selangor, Malaysia). Friday, 23 March 2012. Updated on 2/10/2013: to include latest SPM (2012) questions. When waves change direction. As they enter one medium from another. At an obligue angle. If a wave moves from one medium into another at right angle. There is no refraction. Because there is no change in direction of the wave. Because a wave moves at different speeds in different media. Is best described as either a single-colour. And, c...

O-Level and IGCSE Yrs 10/11 students. (Published By: Tan of PJ, Selangor, Malaysia). Tuesday, 27 March 2012. A physical quantity is to make an acceptable estimate. Of the true and actual value of the quantity. All measurements in science are Man’s attempts to determine the true and actual value of the relevant physical quantities. No measuring instruments is perfect;. No handling of measuring instrument (i.e. technique of measurement) is perfect; and,. In measurement is the difference between. And microm...

Physics for SPM: The Scientific Method
http://physicsf45spm.blogspot.com/2012/03/scientific-method.html
O-Level and IGCSE Yrs 10/11 students. (Published By: Tan of PJ, Selangor, Malaysia). Tuesday, 27 March 2012. Updated on 2/10/2013 to include latest SPM 2012 questions). Before the time of Galileo Galilei (1564 1642), natural phenomena were commonly explained by pure thinking alone – for this reason, physics was then also known as natural philosophy. However, this pure thinking or philosophical approach had led to many false beliefs - among which were that:. Our Earth was flat;. Using the scientific method.

O-Level and IGCSE Yrs 10/11 students. (Published By: Tan of PJ, Selangor, Malaysia). Thursday, 12 September 2013. The angle of incidence, Ө. The angle of reflection, Ө. The incident ray, the reflected ray and the normal lie in the same plane. The normal is the line drawn at right angle to the mirror where the ray strikes. The angle of deviation of a ray is the angle between what would have been the direction of the original ray and the actual direction of the deviated ray.). Image Formed by Reflection:.
