Electromagnetic radiation

Spectroscopy is the study of how matter and electromagnetic radiation interact with one another. In this experiment, we are observing and recording the emission of photons with wavelengths on the visible light spectrum. To understand…

Comparison of the (EMS) 1rst Hypothesis: we believe that High Frequency has more energy than low frequency. Explanation: For this hypothesis, we found that our calculations were wrong and we tested this by using the electromagnetic spectrum: radio wave, microwave, radiation, infrared, visible light, ultraviolet, X-rays and gamma rays. We went outside and made a simulation by walking and each group was one of the spectrums and we looked at how many more laps one group did than the other and we…

Introduction Thermodynamics is an essential concept examined during the construction stage of houses, especially in the countries reaching extreme temperatures, such as Australia. By understanding the physics involved in thermodynamics throughout the construction stage of houses, such as heat transfer involving different colours and thicknesses, it is possible to re-examine the insulation of houses in hot countries. Such a report can lead to finding the most appropriate colour and thickness for…

electrons are subjected to a voltage, resulting in a voltage difference between the cathode and the ground in a manner that minimizes electronic collisions. The cathode ray is controlled by the electromagnetic lenses, generated by the coils that circulates around the tube. The effect of the electromagnetic lenses can be adjusted by changing the electricity flowing in the coils. The cathode ray is focused into a narrow beam and shot directly to the specimen. Formation of an image of…

1. Color Color is a piece of the electromagnetic range and has dependably existed, however Sir Isaac Newton gave the first clarification of shading in 1666. Newton passed slender light emission daylight through a crystal situated in a dim room. Obviously all the noticeable range (red, orange, yellow, green, blue, indigo, and violet) was shown on the white screen. Individuals as of now realized that light went through a crystal would demonstrate a rainbow or noticeable range; however Newton 's…

Chapter 5 Proximity Sensor 5.1 Introduction A proximity sensors is the sensor able to detect the presence of nearby objects without any physical contact. A proximity sensors often emits an electromagnetic field or a beam of electromagnetic radiation, and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor target demand different sensor. For examples a capacitive or photoelectric sensors…

1a) The incandescent bulb produced a continuous spectrum because all wavelengths were observed. Rutherford’s model predicts that the spectrum of hydrogen should be continuous as well. b) During the demonstration, a continuous spectrum was observed for incandescent light and a line spectrum was observed for hydrogen; therefore, my observations seem to contradict with Rutherford’s model. Rutherford hypothesized that atomic spectra should always be continuous because he believed that electrons…

particles of a medium. Some waves must travel through matter, known as the medium (mechanical waves). And when they travel through the medium they cause the particles to vibrate. Some types of mechanical waves are sound waves and ocean waves. Electromagnetic waves, on the other hand, are waves that do not need to travel through a medium. They are disturbances in both the electric and magnetic fields. These waves can travel through a vacuum (empty space) because they don't require a medium to…

which can be aided by infrared spectroscopy. IR spectroscopy deals with the infrared region of the electromagnetic spectrum. This region is light with a longer wavelength and lower frequency than visible light. (Wikipedia) IR Spectroscopy is a method to identify substances based on their absorption of infrared wavelengths. It is a study of how the molecules of substances can absorb infrared radiation and convert it into heat. (Cole) A machine called an infrared spectrometer applies infrared…

Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or…
