Electric light

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 travel through. Some examples on them are light, X-Ray and infrared rays. Both these types of waves are classified according to the direction the particles, it…

“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…

Introduction Interior design is an exciting and rewarding occupation. It revolves around creativity, intellectual fulfillment, and also provides a lifetime of personal appeal. Interior design is vital, vibrant, and dynamic, meaning that as the world changes so does life around us, and design keeps up with the pace. Since we are also evolving and advancing into the future with new technology and ideas, the interior of a space is never truly finished, because it can always be enhanced by the…

in the universe: a black hole. Black holes interact with light, reflecting so little, that they do not let any escape. That is dark but the intense energies created by black holes in the process of eating stars is anything but dark. The level of complexity of light and dark that we see in the universe can also be seen in James Baldwin’s short story “Sonny’s Blues”. In “Sonny’s Blues”, James Baldwin looks past the normal literary uses of light and dark imagery as representing good and bad, but…

Taking a walk in Tate Modern I noticed that the light intensity as well as the light distribution is different in each space: the galleries from the Turbine Hall and the halls. In the galleries there are glowing light boxes displayed on the ceilings. The boxes are made out of glass and a steel frame. In addition to these there are also attached movable light bulbs on the steel skeleton of the boxes. In his article, John Hirst describes the inside of a light box: ‘Internally the boxes have…

Effects of Social Media Before social media existed the way people met each other was through face to face communication. Now when walking down the sidewalk people pretend to be on their phones so they do not have to talk or acknowledge each other. People now days lack social/people skills. Social media over the past couple of years have taken control of people’s lives. Social media is not just taking over people’s lives it is also effecting people’s brains, behavior and thinking. Social…

iii) Light intensity, cm-2 Formula of light intensity = (1/distance2) = cm-2 Eg : for 10cm = 1/((10.00cm)²) = 1/(100 cm²) =0.0100 cm-2 Distance of leaf discs from the light source (±0.05) cm Light intensity (cm-2) 10.00 0.0100 15.00 0.0044 20.00 0.0025 25.00 0.0016 30.00 0.0011 35.00 0.0008 Table 6: The table shows the…

As clearly seen in the beginning of the documentary we see the phone box, shrouded in darkness with only one very faint source of light. This immediately provokes the audience to question: Why? What’s happening? And thus get the audience to truly become curious as to what they are looking at and to what might happen next. This technique of using the darkness rather than avoiding it…

always remember how they were treated, and the call lights are in place to help nurses deliver better care. Last semester, the nurse manager said that the patient satisfaction ratings were down to around a range of 40%. This number is extremely alarming. Most other area hospitals have patient satisfaction ratings are in the 80 to 90% range. After hearing that astonishing information, it became apparent why the numbers were so low. Call lights were not being answered by the nurses. Nurses only…

that naturally light up! In fact, many different types of creatures that live in the water light up: squid, eel, jellyfish, which can be seen to the right in figure one, and many various species of fish have the ability to do such. The ability, called bioluminescence, is defined as “ the emission of light from living organisms”, according to Merriam-Webster. More informally, it is considered the ability where a creature, which can live either on or off-land, can produce their own light. Some…
