Document Summary
Not governed by the same physical laws of larger objects eel = kq1q2/d. Characterized by length, height, and # of waves that pass through a certain point in space in a given time. Wavelength ( ) - distance between identical points and adjacent waves (m) Frequency ( )- # of waves that pass through a point in space in 1 second (s-1) Amplitude - vertical distance from endpoint to a crest/trough. Electromagnetic radiation (light) - em wave has an electric eld and a magnetic eld component. Two components have the save , same c = 3. 0x108 m/s or 186,000 miles/s c = v. Very interested in how em (light) interacts with atoms and molecules. The of green light from a tra c signal is 522 nm. Stove top that glows red (light bulb glows white) Classical physics struggled with trying to explain why when temperature increases, the energy of radiation does not uv catastrophe .
