Overuse of sunscreen and sun block‚ which contain many potentially dangerous chemicals‚ could be even more harmful than exposure to the sun’s rays. Sunlight is produced through nuclear reactions in the sun’s core. Originally born as energetic gamma rays‚ after billions of collisions with matter‚ this radiation reaches the surface and escapes into space (Mitalas). The sun radiates light to the earth‚

How weather effect your mood? Weather can have more than a little impact on your mood. Researchers in Germany branched out beyond just sunny and cloudy and looked at temperature‚ wind‚ sunlight‚ rain and snow‚ air pressure‚ and how long the days were. The study was led by Jaap Denissen of Humboldt University in Berlin. The study had 1‚233 participants‚ all living in Germany at the time. Most of the participants were women‚ the average age was 28‚ with ages spanning from 13 to 68 years old. Study

explain how your life might be different if you could make your own food through photosynthesis. First of all if we were to be able to make our own food trough photosynthesis‚ we should have chlorophyll‚ which is the important pigment in absorbing sunlight. As an effect we will all be green in color. This may be good as there will be only one race but then again our cell must be modified in order for that to happen. Most important our cells must contain chloroplast where photosynthesis occurs. It would

There are plenty of films based on a true story and various ways to use lighting as a part of Mise en Scéne to make all of those films seem more realistic or in sometimes unrealistic whichever is the director’s and cinematographer’s take on the story.

the most. A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by water droplets present in the atmosphere. The water droplets act like small prisms. They refract and disperse the sunlight then reflect it internally and finally refract it again when it comes out of the rain drops. Due to the dispersion of sunlight and internal reflection by the water droplets we see the rainbow colours. Tyndall effect :When a beam of light passes

photic zone is the area of an ocean that is shallow enough for sunlight to penetrate through the water. The aphotic zone is the darkest‚ deepest area of the ocean. This is how marine biologists separate this marine biome. Normally‚ the photic zone water is warmer and the aphotic zone is colder. There are two reasons for this. One is because the sunlight is able to go through the water in the photic zone‚ heating the water. The sunlight can’t reach the water in the aphotic zone so it says cold. The
