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

Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

In this report‚ the absorption of heat in white‚ black and silver will be explored. Infrared radiation is invisible radiant energy‚ it lies between the visible light and the microwave portion of the electromagnetic spectrum. Heat is the main source of infrared energy‚ heat is produced by the movement of atoms and molecules. This experiment was conducted to investigate how black‚ white‚ and silver cans would absorb heat. The electromagnetic spectrum is made up of gamma rays‚ X-rays‚ ultraviolet‚

Purpose of POWER System protection The purpose of any power system is to generate‚ transmit‚ and distribute electricity to the consumer in a manner that is safe‚ reliable‚ and economical; both in the short and long term. Under normal operating conditions‚ the currents‚ voltages‚ power‚ and energy associated with such systems are all matched to meet the system’s design requirements with respect to reliability‚ quality‚ safety‚ and economy. To ensure maximum returns on the large or expensive investments

Consumer protection Act Introduction A consumer protection Act‚ 1986‚ provides for the better protection of consumers. Unlike existing laws which are punitive or preventive in nature‚ the provisions of this Act are compensatory in nature. The act is intended to provide simple‚ speedy and inexpensive redressal to the consumers’ grievances‚ award relief and compensation wherever appropriate to the consumer. RIGHTS ENJOYED BY CONSUMER Right to be protected against the marketing of goods

"sellers market" to a "buyers market" where the choice exercised by the consumer is influenced by the level of consumer awareness achieved. By "consumerism" we mean the process of realizing the rights of the consumer as envisaged in the Consumer Protection Act (1986) and ensuring right standards for the goods and services for which one makes a payment. This objective can be achieved in a reasonable time frame only when all concerned act together and play their role. The players are the consumers represented

Burnett | 3/11/2013 | | Radiological protection deals with methods and efforts of safeguarding people and the surroundings from the deadly effects of ionizing radiation that includes electromagnetic radiation and particle radiation. Sometimes radiation cannot be controlled or contained and accidents take place causing radiation leaks. For this reason‚ protocols and radiation safety has become a pre-curser in our

About Radiation: Radiation is an energy that is transmitted in the form of waves or tiny particles. These are electromagnetic waves‚ which are classified as ’ionizing radiation’ and ’non ionizing radiation’. Electromagnetic radiation is when an object gives out electromagnetic radiation. For example when you on a torch light‚ the light is an example of radiation. Ionising radiation has more energy than non ionising radiation. Therefore it is enough to cause chemical changes by breaking chemical
