1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving then when the sound gets closer‚ the volume will increase and when the sound passes by you‚ the volume will start decreasing. 2. Select the boy icon. Select the

China‚ such as Kunming Dali Industry and Guangzhou Shining Trading‚ are riding on Singapore’s “slim wave” to make money. In Asia‚ the idea of a slim figure has turned from a Hollywood-induced dream into an obsession. The glossy magazines geared toward women have covers adorned with slim‚ petite models. Local newspapers constantly feature advertisements portraying slim actresses and models who have transformed themselves from bloated balloons into sunbathing beauties. Slimming is increasingly

Demonstrative communication includes nonverbal and unwritten communications. Facial expressions are the most common among all nonverbal communication. Demonstrative communication reinforces verbal communication. For example‚ dressing properly‚ and a friendly demeanor can speak volumes about the kind of speaker it will be during a presentation. Demonstrative communication can be done by nonverbal action for example‚ a smile on a speaker’s face when giving a speech or presentation‚ the facial expressions

Uses of Electromagnetic Waves Radio Waves * TV and FM radio (short wavelength) * Direct line of sight with transmitter (do not diffract) * Medium wavelength – travel further because they reflect from layers in the atmosphere * Used for transmitting signals. Microwaves * Microwaves are used in satellite television broad casting. * It is used to transmit mobile phone signals between Mast‚ which may be up to 20km apart. * Microwaves are absorbed by water molecules

Essay 1: Light and Color The fascinating properties of light are not all detectable to humans‚ because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each

Dispersion Of White Light by a Glass Prism: When a beam of white light is passed through a glass prism‚ it is split up into a band of colours called spectrum. This is called dispersion of white light. The spectrum of white has the colours violet‚ indigo‚ blue‚ green‚ yellow‚ orange and red (VIBGYOR). The red light bends the least and the violet light bends the most. A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by water

A pantomime uses its technique‚ in where a story is told using just music‚ sounds‚ and the motion and facial expressions. The scene I find memorable is where the main character firsts

Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs and circuits
