ASTA01H3 Lecture 6: Lecture 6--11, Study Guide
Document Summary
Lecture 6: escape velocity: the speed necessary for a projectile to completely escape a planets gravitational field, radiation, em radiation. visible light is the particular form of em radiation that our eyes espond to. Invisible radiation: infrared, ultraviolet, x rays and gamma rays. all travel at speed of light and travel in form wave through space: wave properties. period is amount of time required wave pattern to repeat itself. the angstrom is 0. 1nm or 10-10m: charged particles. changes in the electric field of the particle travel out through the electric filed as em waves. the frequency at which particle vibrates determines the frequency of the em waves www. notesolution. com. If a charged particle begins to vibrate its electric field changes and the resulting disturbance travels through space as wave: em waves. a change in one field causes change in the other. these fields are always perpendicular to eachother.
