Radio Waves In the modern society‚ radio is the most widely used medium of broadcasting and electronic communication : it plays a major role in many areas such as public safety‚ industrial manufacturing‚ processing‚ agriculture‚ transportation‚ entertainment‚ national defense‚ space travel‚ overseas communication‚ news reporting and weather forecasting. In radio broadcasts‚ they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude

to point through a medium is called a ___. a. period b. periodic wave c. wavelength d. pulse Answer: D A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance. 2. If the particles of the medium are vibrating to and fro in the same direction of energy transport‚ then the wave is a ____ wave. a. longitudinal b. sound c. standing d. transverse Answer: A In longitudinal waves‚ particles of the medium vibrate to and from in a direction parallel

Little Red Riding Hood The way in which women are represented and defined throughout Western culture is leading somewhat of a controversy between the male and female genders. Within the chapter‚ “Dreams‚ Fears‚ Idols”‚ by Simone de Beauvior‚ she expands upon the numerous problematic ways in which a woman is represented in these cultures. In most situations within fairytales or short stories‚ women are portrayed as the “damsel in distress” or the “weak link”‚ meaning that they are powerless and are

Electromagnetic Waves It was once the great Scottish physicist James Clerk Maxwell (1831-1879) who had presented that electric and magnetic fields unstable together can form a spreading wave‚ appropriately called an electromagnetic wave. The properties of an electromagnetic wave are as follows: 1. They can travel through a vacuum at the same high speed‚ which is much faster than other types of waves that travel through a material. 2. They show the normal wave properties of reflection‚ refraction

Unit: Sinusoidal Waves Subject: Advanced Algebra/ Trigonometry Overarching Question: What are real life applications of Sinusoidal Waves? First and Foremost‚ Sinusoidal Waves are waves that can be described to have a sine curve‚ usually repetitive. Sine waves are a part of the mathematic topic‚ Trigonometry. However‚ these types of waves may be found in various other scenarios. For instance‚ many are found in nature‚ you just have to observe with care. This means to say that they aren’t just

INFRARED WAVES * Infrared (IR) light is electromagnetic radiation with a wavelength longer than that of visible light How They’re Made: Infra red waves are just below visible red light in the electromagnetic spectrum ("Infra" means "below"). You probably think of Infra-red waves as heat‚ because they’re given off by hot objects‚ and you can feel them as warmth on your skin. Infra Red waves are also given off by stars‚ lamps‚ flames and anything else that’s warm - including you. The detector

Water Waves By Anna Introduction Water waves have been around for years; learning about water waves can help you understand the outside world. Water waves can be used in many ways‚ but they can also be harmful‚ too. When were they discovered? Water waves have been around since the creation of the earth‚ but Isaac Newton came up with a theory; after studying waves in about 1687. What is the biggest wave? In 1958 the biggest tsunami wave was recorded. How much harm can water waves really
