The energy of electromagnetic waves are measured in the electromagnetic spectrum, a big graph showing the different wavelengths and frequencies of electromagnetic waves. It ranges from radio waves, which are the weakest, to gamma rays, the strongest -Only a very small part of the spectrum is visible to the human eye, called the visible light spectrum. These colors are the colors of the rainbow.
Why Is Light so Important to Us? Light is the triggering force behind many chemical, biological and physiological changes in life forms on Earth. It provides much needed energy, and it also forms the foundation that aids in visibility. Light kick-starts food chains, both on land and in the sea. It acts as a catalyst during photosynthesis in plants, and it provides sustenance for the survival.
The familiar compound light microscope is a series of lenses (hence “compound”) that focus visible light in such a way as to produce a magnified image. A single lens, often called a magnifying glass, cannot generally magnify images as much as a series of lenses although Antony van Leeuwenhoek, the first microbiologist, used a simple, albeit exquisitely crafted, lens to discover single.
