Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight. When animals digest

What are greatest moments? Are they the best moments in life‚ the ones we remember or the events we try to forget? When asked‚ people generally seem to say the moments they consider the best: Weddings‚ graduations‚ the birth of children and personal enlightenment. The key word here‚ it seems‚ is Greatest‚ and Great does not necessarily mean best‚ it means most important. The Greatest moments in life are just as likely to be tragedies as they are triumphs because bad moments are just as likely to

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. Seeing colors and shapes is second nature to us‚ yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from the

Dark Energy VS Dark Matter Dark Matter Dark Matter is the name given to mass that emits no detectable radiation. ‘’Dark Matter accounts for the galaxies rotating about "local groups" in tighter orbits than we expect from our observations. Gravity is stronger than we can account for unless there is some matter we cannot see. We are much more certain what dark matter is not than we are of what it is” (Feild‚ Ann‚ 2013). Scientists think dark matter is made of particles called WIMPS‚ "weakly

Armadillidium vulgare‚ naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment‚ a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light was hung above one chamber of another double-chambered petri dish while the other

The Nature of Dark Matter We observe the universe around us through many scientific means. However it is through the electromagnetic spectrum‚ that is everything from radio waves to gamma waves‚ that we learn about the objects in our world and beyond. However we can also learn about our universe through indirect means‚ such as the effect of gravity on light as well as larger objects like our galaxy. In fact it is this indirect method of observation that has led us to the discovery of extra-solar

Dark energy what is it? Dark energy is a unknown energy said to take up 70 percent of the universe. The energy is a repulsive gravitational effect that is causing the universe to accelerate out-ward. No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy‚ yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comparing

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye‚ and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm)‚ or 400×10−9 m‚ to 700 nanometres – between the infrared‚ with longer wavelengths and the ultraviolet‚ with shorter wavelengths. These numbers do not represent the absolute limits of human vision‚ but the approximate range within which most people can
