A cura della 4 A LS Docente Lucia Russo A wave is an oscillation accompanied by a transfer of energy but not substance that travels through. Sources and detection . Ravi . kumar. . Kopparapu. Center for Gravitational-Wave Physics (CGWP) . Gravity. Einstein’s General theory of relativity :. Gravity is a manifestation of curvature of 4- dimensional (3 space + 1 time) space-time produced by matter (metric equation ? g. and. Perception of sound. Lecture 8. Pre-reading. : . §16.3. Fourier theorem. Why sine waves?. Any wave shape can be represented as a superposition of normal modes (components). §15.8. Sound as Pressure Wave. Learning Objectives. Know why light is said to travel in waves.. Know what polarisation is.. Know how diffraction patterns occur.. Success criteria. Explain how experiments show that light travels in waves. . Earthquake. – shaking and trebling that results from the movement of rock beneath Earth’s surface.. Plate movement causes earthquakes from stress and faults in Earth’s crust. When the rock breaks earthquakes happen. Doppler Effect. ~apparent change in frequency of a wave due to the motion of the source of the wave.. If the object is moving towards the observer the frequency will appear to increase. If the object is moving away from the observer the frequency will appear to decrease.
