Light Intensity of Incoherent Lights

An investigation to measure the percentage light transmission, using a colorimeter, through a solution, from pH 2 – pH 9, in which jelly cubes were immersed over a 24 hour period

14. Different levels of brightness are due to different levels of heat, and different distances.

Electromagnetic radiation between the wavelengths of 380 nm and 740 nm constitute light and the human color-vision

Light is a type of energy. Light behaves like a wave because it acts as a disturbance in the magnetic and electric field of space. Light can behave as a particle, because it sends all its energy to one place. A particle of light is called a photon. Photons can be absorbed into objects, bounce

Beer’s Law is a direct liner relationship between the absorbance of light are a selected wavelength and the concentration the absorbing species in the solution. (Sullivan 241). Beer’s Law shows a relationship between several concentrations. To determine if the determine our data consistent with Beer’s law, we will plot a graph of absorbance versus concentration with a linear regression

Visible light is an extremely small proportion of the entire range of the electromagnetic spectrum. Visible light ranges from 390nm to 780nm. The theoretical wavelength of the laser was 633nm, indicating a light red. The experimental wavelength calculated from the experiment was 617nm, implying that it is dark orange. The laser used in the experiment emitted a light red color, thus implying that there was a small amount of error that affected the results from the experiment. In the equation ∆y=λL/d, the values of d and the wavelength were provided from the manufactures,

UV light is a form of energy that is used therapeutically and is divided into UV-A, UV-B and UV-C according to the wavelength and location of the electromagnetic spectrum. UV light is absorbed one to two millimeters into the skin and most commonly used to treat skin disorders. Some of the therapeutic effects of UV light are; bactericidal effects, exfoliation,

Like in the above paragraph it is discussed that light is a transverse wave which means that particles in a medium are more perpendicular to the wave energy.  Another type of wave is longitudinal which sound is. This means that the particles in a medium are more parallel to the wave energy. Light is affected by the electromagnetic spectrum.  On the left hand of the spectrum there are long wavelengths, low frequencies, and low energies. On the right hand there are short wavelengths, high frequencies, and high energies. The light’s color comes from frequency and wavelength.  The brightness of light comes from the amplitude and the number of waves. To find a wavelength one can use the equation λ= l*2. The variable λ stand for lamda and l stands for length. Another equation one can use is v= f λ. The variable v stands for velocity, f stands for frequency, and λ stands for lamda.  With this basic understanding of light waves one can now look at the ideas on how different colors one wears at the beach affects how one feels. What colors does one wear in the summer at the beach to stay cool? This is always a question that is asked! Whether at the beach in a bikini or at the amusement park with a tank top light waves affect how light interacts with people.  There is evidence to support both sides of this argument with physics. The first theory is that some believe that white is a

visible light spectrum are known as the non visible light spectrum. The visible is measured

Light is described to be both as waves and photons. Photons are a mass of electric and magnetic fields all bundled together to make electromagnetic energy. It’s the basic unit that makes up all light. This electromagnetic energy is what oscillate sin waves and are right angles to one another. The nature of light also interacts with matter by absorption, reflection, transmission, and emission.

There are six types of light in order from weakest to strongest, radio waves, microwave, infrared, visible light, ultraviolet, x rays, and gamma rays. Some similarities and differences are-

Ultraviolet light, also known as UV light, is a type of electromagnetic radiation. Ultraviolet light comes from the sun and is invisible to the human eye. Although humans are constantly exposed to UV light, too much ultraviolet radiation could be potentially harmful to living tissue. Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies (Lucas 2015). This range is known as the electromagnetic spectrum which is split into

For instance, the speed of light has been measured at roughly 670 million miles per hour (Wile 365). With some math, scientists have learned that light can travel the circumference of earth approximately 7 times each second and that it takes around 8 minutes for the sun’s rays to reach earth. Scientists can now calculate the wavelength, which is the distance between two crests, and frequency of a light wave, but also the energy of a photon at the same time and use the values interchangeably (Wile pp. 352 and 373). The electromagnetic spectrum, the collection of all forms of light, shows that visible light is only a small fraction of all light. The spectrum ranges from energetic gamma, X-ray, and ultraviolet radiation to relatively low-energy light waves such as infrared, microwave, radar, TV, and FM and AM radio. Visible light, also known as the visible spectrum, sits between ultraviolet and infrared. It is the only portion of the electromagnetic spectrum that humans can see (Wile 370). Although much of the spectrum is unperceivable to the eye, it has numerous uses. For example, X-rays are used to find broken bones and treat cancer, infrared light is used in remote controls, microwaves heat food, and FM and AM waves are used in

This paper examines material based on Beer Lambert’s law and spectrophotometry. It shows what happens between the concentration and absorbance of CoCl2 x 6H20 (Cobalt (II) Chloride Hexahdrate). To detect the wavelength and unidentified solution , the spectrophotometry was employed. After everything, in a proper graph we gathered the the data to demonsrate what relationship absorption and concentration have. Moreover, Spectrophotometer, electromagnetic, lambda max were considered to make the experiment a success. A spectrophotometer measures the intensity of light through a unknown solution. The methodology will give you a brief discription of the way the experiment was perfomed. The main ambition of this lab will be demonstrated with the experimental result. All labs were were put into a grap and table. Therefore errors that occurred throughout the lab were explained and what should be done in the future to make a acknowleged lab.

Natural and artificial light have varying properties that affects their capability and appropriateness these properties regularly impact their surroundings. Natural light comes in a spectrum of colours, which are the visible rays. Also on the colour spectrum are shorter wavelengths, named ultraviolet rays and higher wavelengths, known as infrared rays. Both of these are not visible to us. Exposure to the sunlight can help
