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

Radios and microwaves both use radiation from the electromagnetic spectrum Visible light can be split into a spectrum of colours .. from red through the rainbow colours to violet but visible light is just a small part of the whole electromagnetic spectrum All the different types of electromagnetic waves travel at the same speed through a vacum .. the waves can be orderd by wave length remebered that waves with the shortest wave lengths have the highest frequency and the most energy and the waves

The electromagnetic spectrum The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes‚ visible that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves‚ infrared and ultraviolet light‚ X-rays and gamma-rays. Hotter‚ more energetic

Blackbody radiation: a spectroscopic study John Greavu Partner: Nicholas Souhleris TA: Yilikal Ayino (Friday‚ Section 006) April 18‚ 2014 I. PRELAB A blackbody is a body that absorbs all electromagnetic radiation and emits a continuous spectrum‚ such as heated cavern with just a small opening to the outside world. In 1900‚ German physicist Max Planck derived an expression for this blackbody spectrum. Knowing that oscillators emit radiation‚ he assumed that oscillators within the cavern were

Science Essay: We use the electromagnetic spectrum every day it’s the microwave you use to heat your food and the cell phones you use to text! Those are part of the Electromagnetic Spectrum. The light that our eyes can see is also part of the electromagnetic spectrum. This visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow - from reds and oranges‚ through blues and purples!! The electromagnetic spectrum has 7 parts to it‚ radio waves‚ microwaves‚ infrared

INTRODUCTION: The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. Radiation can be said to be energy that travels and spread as it goes. The "electromagnetic spectrum" of an object has a different meaning‚ and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. We tend to witness different radiations of the electromagnetic spectrum without knowing‚ example is the visible light that

Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in

Electromagnetic waves are radiated energy of all different strengths. They’re different from sound waves and water waves because they have the ability to travel through empty space. A vacuum. These are the only types of waves that do not need any type of medium because of photons. Photons are tiny particles that don’t get traveled through‚ but make up electromagnetic waves. Photons travel with the wave at about 300‚000 k/s. also known as the speed of light. The more energy the photons have‚ the brighter

radioactivity is the treatment of cancer. Yes‚ radiation therapy is utilized for treatment of many types of cancers. Radiotherapy: a method to destroy cancer cells by irradiation with radioactive isotopes or X-rays. a. Explain briefly how radioactivity can cure some types of cancer. beta particles can cure skin cancer but not inside the body The main scooby dooby on this is that the biological damage done to some kinds of cells by exposure to radiation is greater than others. And we frequently see
