Light year (ly): distance light travels in one year: about 10 trillion km (10 x 10 km) Pressure: force per area which a volume of material pushes on it"s surroundings. Birth of universe - 14 billion years. Birth of milky way - 13 billion years. Swing by alex"s office hours to touch things. Astronomical unit (distance between earth and sun) Constant and convenient way to measure larger distance: light speed.

Electric field radiates in a circular manner. Electromagnetic wave has the theoretical speed of light. Visible light is a type of electromagnetic wave (radiation) Self-propagating, oscillating electric and magnetic fields perpendicular to each other and to the direction of motion. Number of times per second a crest passes a plane. Wavelength x frequency = v = c.
