What is physics all about explain the importance of it physics is the study of matter and energy modern physics studies the extremely small (subatomic particles), the extremely large (galaxies), the extremely fast (the speed of light. All about light-physics filed under: essays tagged with: light in 1678, dutch physicist, christian huygens, believed that light was made up of waves vibrating up and down perpendicular to the direction of the light travels, and therefore formulated a way of visualising wave propagation. Light on physics for idiots | light is energy that we can see it is given off (emitted) by matter when it is hot or in some way excited this radiation/light can be thought of as both a wave and a particle sometimes it behaves like one, at other times it behaves like the other.
The physics of light astronomers have a disadvantage in many respects because they are some basic physics here are some main points you need to understand: light behaves like a the width of a wire that makes up a paper clip is about 1 mm red light has a lower frequency than blue light. It's all about colors man has always been fascinated by light and has constantly striven to unravel its mysteries the speed of light in empty space and in air is generally rounded up to 3 x 108 m/s or 300,000 km/s this means that light takes around 13 seconds to travel from the moon to the earth. About mini physics in terms of classical wave theory, light is an electromagnetic wave that is capable of passing through free space or through a material medium in the form of varying electric and magnetic fields. Light and sound are two of the most important ways to understand the world around us the sun is earth's main source of energy and light our eyes and brain work together to translate that light into what we see while our ears pick up sound vibrations and translate them into meaningful messages.

Light is the common name for electromagnetic radiation with wavelengths of 400-750 nm this term is sometimes expanded to include ultraviolet and infrared radiation this invention brought about a true technological revolution yaron gross department of condensed matter physics. Another interesting fact about physics is that the famous physicist, stephen hawking who proposed the existence of black hole discovered a radiation called hawking radiation which makes the black hole glow and gives off light across whole spectrum 9 the touch screen of your phone is based on. All about physics wednesday, march 21, 2012 light plays an important role in life light is electromagnetic radiation that is visible for human eye, and is responsible for the sense of sight.

Join physics forums today the friendliest, high quality science and math community on the planet everyone who loves science is here light (a whole bunch of photons) exerts a pressure on the scale's surface. Light physics written by: glenn stark light, electromagnetic radiation that can be detected by the human eye electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metre to radio waves measured in metres. The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make.
Physics is a specific area of study in the field of science that focuses on the makeup and properties of both energy and matter, as well as how the two interact together one of the most important facts to understand about both light and sound is that both are forms of energy that move in waves. Light is radiant energy, an electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight it is the most popular form of energy, the wavelengths visible to humans range between 380nm (nanometers) to 740nm it takes about seven minutes for light from the sun to reach.
