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‚ visible‚ infrared‚ microwaves and radio waves. What separates these is the

diffraction and interference are observed‚ waves are involved. Waves do not have mass or charge. Photons All electromagnetic radiation consists of photons. A photon is a packet of energy‚ or a quantum of electromagnetic energy. Gamma-photons are the most energetic out of all the types of photons. The energy of a photon is directly proportional to the frequency of the electromagnetic radiation of which it is a part of‚ so high frequency radiation means high energy

(13 points) A Doppler radar is an important tool used to measure the velocity and direction of a moving object. The Radar actually has transmitters that produce and release electromagnetic waves in the form of microwaves or radio waves. These waves are sent out and when they reach something they reflect or

Ms. Wilson Chem‚ Blk 10 31 October 2012 Atomic Emission Spectra Lab Atomic spectroscopy is the determination of elemental composition by its electromagnetic or mass spectrum. An arrangement of all wavelengths of electromagnetic radiation is called the spectrum; the plural being spectra. As light passes through a prism‚ the frequencies of light emitted by an element separate into separate lines to give the atomic emission spectrum of the element. There are two spectrums in the lab: the incandescent

which makes Blue the only available light we see‚ and heres why! Theres alot of explainations when it comes to understanding why the sky is Blue. To understand why the Sky is Blue‚ you must first understand the basics. Such as the different Electromagnetic Waves‚ Colors of the Rainbow‚ Rayleigh Scattering‚ and the Different Light Spectrums. Color is simply defined as the sensation produced by the effect of light waves striking the retina of the eye. The color of something depends mainly on which

At the 10m position‚ half way up‚ the net force on the ball is A. 2mg. B. mg. C. mg/2. D. mg/4. B is correct‚ as a vector diagram would show. Other choices show carelessness or confusion between force and speed‚ and what constant acceleration means. 2. When you drop a ball it accelerates downward at 9.8 m/s2. If you instead throw it downward‚ then its acceleration

Abstract— the project is enlightening us about the characteristics and properties of electromagnetic wave .It also include radar‚ how does it works‚ its components and application of EM Wave in radar. 1. Electromagnetic Waves Electromagnetic waves are composed of oscillating electric and magnetic fields at right angles to each other and both are perpendicular to the direction of propagation of the wave. Electromagnetic waves differ in wavelength. Fig1. Propagation

Danielle 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
