Light pollution Light pollution‚ also known as photo pollution or luminous pollution‚ is excessive artificial light. This phenomenon is pronounced around urban centers‚ where city lights diminish the view of stars and planets. In addition to brightened skies around cities‚ light pollution also refers to any outdoor light that creates glare and interferes with the natural night environment. Cause Light pollution results from outdoor lights aimed

Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important.

Photosynthesis simply means the conversion of light energy into chemical energy by living organisms. In photosynthesis‚ the raw materials are water and carbon dioxide. Energy is taken from sunlight and the end products give out glucose and oxygen. It is the most important‚ naturally occurring process

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

Brooks was born on June 7‚ 1917 and began to have an interest in poem early in her life. Her first poem was published at the age of thirteen in the American Childhood Magazine in 1930. Today she is known for having more than twenty books of poems published like “The Children Coming Home”

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

Cellular respiration and photosynthesis are fascinating‚ complicated‚ and important processes that are essential to life. Cellular respiration exists in animal and plants‚ whereas photosynthesis only exists in plants due to the chloroplast organelle. Cellular respiration starts with glucose‚ and oxygen and the photosynthesis process on the other hand starts off with the absorption of photons of light from the sun.While the end products of cellular respiration are carbon dioxide‚ water‚ and ATP‚ the
