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

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

Explain errors of omission and errors of commission. Ans - == Errors of commission == An error of commission occurs when you record an incorrect value in posting. Such errors include original entry errors‚ transposition errors‚ calculation errors and reversal of entries. An original entry error occurs when an incorrect figure is recorded and posted. A prime instance of this is the ten-key error‚ where you accidentally hit the number above the correct key. For example‚ if you enter 7‚ instead

order to present their experiences of Korean Wave‚ this paper will be divided into four sections. The first section will describe demographic characteristics of the Korean Wave group in Asia. The second section is a literature review refering to the cultural background of Korean Wave including Korean pop music‚ drama‚ food and so forth. This is followed by an interview conducted with Helen and Hana giving information about their experiences of Korean Wave. The final section will state some steretyping

interpreted from the poem‚ “From the Wave”‚ by Thom Gunn. The first meaning is the actual and literal meaning of a surfer catching a wave. The second is a metaphorical meaning. This meaning describes the ups and downs of a human being’s life. Readers know the speaker is actually talking about surfers‚ because Gunn describes the how it feels to actually catch a wave. The speaker says that “Their pale feet‚ curl‚ they poise their weight / With a learn’d skill. / It is the wave they imitate. / Keeps them so

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

Trial and error is an experimental method of problem solving‚ repair‚ tuning‚ or obtaining knowledge. "Learning doesn’t happen from failure itself but rather from analyzing the failure‚ making a change‚ and then trying again." This approach can be seen as one of the two basic approaches to problem solving and is contrasted with an approach using insight and theory. However‚ there are intermediate methods which for example‚ use theory to guide the method‚ an approach known as guided empiricism.

Seismic waves‚ which are waves of energy that travel through the earth‚ and are a result of an earthquake‚ explosion‚ or a volcano that imparts low-frequency acoustic energy. There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When
