If this is not possible or natural light is not sufficient‚ then alternative light sources should be those that do not cause discomfort‚ after a prolonged period eg‚ fluorescent bulbs. Noise: The level of noise around a classroom should be taken into consideration‚ as this can cause distractions and cause an area of work to become unsuitable. Specific risks to individuals: Individuals may have specific risks to take

PROCEDURE Part 1: White light a.) Starting with the incandescent light source‚ I took a spectroscope and aimed it toward the center of the light. b.) Observe the spectrum created. c.) I then‚ repeated the same process with the light coming from the fluorescent light source. Part 2: Gas Tubes a.) I then moved to the gas tubes‚ starting with Helium. I placed myself at in front of the light tube & aimed the spectroscope for the center. b.) Repeated process with the remaining gases‚ Ne and Hg.

1.Ventilation: The modern concept of ventilation implies not only the replacement of vitiated air by a supply of fresh outdoor air‚ but also control of the quality of incoming air with regard to its temperature‚ humidity and purity with a view to provide a thermal environment that is comfortable and free from risk of infection. * The EPA has identified indoor air quality as one of the five most urgent environmental risks to public health. * The majority of all infections and allergies are

Many students prefer to work with less light‚ particularly to avoid the glare of fluorescent lighting. Separate switches control several banks of lights in the classroom. Some banks have had all but one fluorescent tube removed. For those concerned about the effects of reduced lighting on students’ eyes‚ current research reveals that even when the light is reduced markedly‚ the eyes will not be injured

Finally‚ we will measure the absorbance of Copper sulfate solution as a function of wavelength. Experimental Method: We start our experiment by looking through a Spectroscope at the outside sunlight‚ a regular light bulb (incandescent) and a fluorescent light. This will give us a good observation on what is continuous and what will be Line spectra. During observation‚ it is recommended not to look directly in to the sun. We will then have to record the wavelengths for each line spectrum for the

Thomas Edison and Nikola Tesla Both men were great inventors of their time and made many inventions. Tesla made the first AC motors and Edison made the first DC motors. Edison made the first incandescent light bulbs and Tesla made the first fluorescent light bulbs. Both men lived well past their 80’s. What many people didn’t know is that they were rivals. Edison had a rival in the race to develop electricity. His name was George Westinghouse‚ and he was very interested in alternating current

We as consumers can purchase compact fluorescent light bulbs that use less energy and last longer than incandescent light bulbs. And the next time you’re looking to purchase a new vehicle that is fuel efficient like a hybrid car which combines gasoline engines and electric motors. I think knowledge

By the way change your regular light bulbs with a compact fluorescent light bulb. Did you know that it can save 150 pounds of carbon dioxide a year? People! Take advantage of the sunshine and use solar panels. People should drive less. They should avoid using transportations that uses fossil fuels .Did you know that
