Chapter 2: EM Waves Review • The force of gravity between two objects decreases rapidly with the separation distance, and increases with mass. • The acceleration experienced by a falling object due to earths gravity is independent of the mas of the object. • A mars-sized and a Jupiter-sized planet both orbit a star at the same distance. The mars-sized planet has the same orbital period when compared to that of the Jupiter-sized planet. • W=mg • acceleration=(gravitational mass * G)/ inertial mass • acceleration=F/m What is a wave? • Waves are a type of disturbance that can propagate or travel • Waves carry information and energy • A disturbance to a medium that travels in a function • Has a temporal quality • Vocabulary: oscillating , pulse What are the main properties of waves? • Period (T): time between crest (or trough) passages • Frequency (f): rate of passage of crests ( or troughs), f=1/T unit: Hertz or cycles/sec o Crest, trough. Wavelength (lambda), amplitude (A), velocity=wavelength * frequency • Different waves travel different distances at different speeds What two things do all waves transport? • Waves carry information and energy, light Light travels at a constant speed, c, the speed of light Electric Force • Opposites attract, like repels • Oscillating charges radiate • All objects have temperatures greater than absolute zero – random thermal motion • All objects radiate • No sound if there is no air - vacuum • Radiation cannot be seen from many ordinary objects because there is not enough heat, its in a different wavelength and frequency What are some examples of electromagnetic radiation and what are the different ways in which we might experience them or make use of them? • The color of visible light • Electromagnetic radiation o Visible - see, infrared - heat, radio – communication, UV – sunburn, X-rays – medical, gamma – highest Review • The bending of light that occurs when moving between media of different densities is called refraction • If the wavelength of light increases, the frequency must decrease • The color of visible light is determined by its wavelength and frequency
