OPTION A - SIGHT AND WAVE PHENOMENA 1. Standing (or stationary) waves Formation of standing waves : When two identical waves travel along a string in opposite directions (ex : flick a rope attached at the other end)‚ they will superpose and create a standing wave (use animation to visualize what happens). Nodes‚ antinodes. Differences between progressive and standing waves : Wave profile doesn’t progress ; All points between two nodes are in phase (they all reach their maximum at the

2014 Moral Standing on Abortion To say that a person has moral standing is to give consideration to his or her wellbeing. According to Robert M. Veatch’s The Basic of Bioethics‚ moral standing is believed to be “that humans (at least normal humans) have moral standing [as well as] other animals” (27). Moral standing is determined by the physical or mental capacities of self-awareness or rationality. However‚ controversy arises when determining when one actually has full moral standing. Abortion

When moving and positioning an individual it is important to ensure they are not moved more than their body is capable of‚ as muscles can only move bones at the joint as far as the joint allows. It is also important to move and handle correctly to ensure nerve fibres are not damaged as they are delicate structures and also

YAMBAO‚ Monn Juleuse F. mjfyambao@gmail.com E304: Kundt’s Tube: Velocity of Sound in Solid METHODOLOGY Two experiments were done last time due to some circumstances that made the class to lack time and to be late compared to the official class syllabus. The students were able to accomplished the job by equally dividing the time into two. The first experiment was about Kundt’s tube. In this experiment‚ longitudinal sound waves will be produced in a metal rod and an air column. Using the properties

Resonating Air Column Expt. # 8‚ Physics 105‚ fall 2010 (reference only) Aim: To determine the speed of sound in air at room temperature using resonating air column (1). Apparatus: Resonance apparatus‚ four tuning forks‚ rubber mallet micrometer caliper‚ can of water and paper towels (1). Description of the apparatus: The apparatus consists of a 110 cm long uniform graduated glass tube of 1(1/2) diameter connected to a rubber tubing and a water

that travels through all forms of matter. The air molecules vibrate in the same direction as the sound wave moves. The modes of vibrations associated with resonance in objects like strings or air columns have patterns called standing waves. The resonance occurs when the standing wave moves in the opposite direction to the medium’s movements‚ or when it arises from the combination of reflection and interference such that the reflected waves interfere with the incident waves. Nodes are the places where
