- The light from a red laser pointer has wavelength6.35 * 10^-7 m in vacuum. When this light is sent into a transparentmaterial with relative permeability 1.00, its wavelength decreases to3.47 * 10^-7 m. Find the frequency of the light in vacuumThe back wall of an auditorium is 26.0 m from the stage. If you are seated in the middle row, how much time elapses between a sound from the stage reaching your ear directly and the same sound reaching your ear after reflecting from the back wall?Two waves travelling in the same direction are given by: y1 = 0.2 sin(2rx-20t+p) and y2 = 0.2 sin(2Ttx-20t), where x and y are in meters and t is in seconds. If the %3D two waves start at the same moment, then the path difference, Ax, corresponding to a fully destructive interference is:
- Blue light travels with a frequency of 6.7 ×1014 Hz in air. Its frequency will ________when traveling in diamond. decrease stay the same increaseLight with frequency 6.96E14 Hz travelling in vacuum enters a transparent material that has index of refraction equal to 1.72. What is the light wavelength in the material (in m)?Have seen some wrong answers by repeating the question which I don't want :(( Please don't answer like previous one You have been asked to predict the wave heights incident on the Fremantle railway bridge due to a wave train with offshore wave height of 1.15 m and period 14 s. The following information is given: (a) refraction analysis indicate that the spacing between the orthogonals is one half the deep water spacing. (b) water depth at the entrance to Fremantle harbour is 10m whilst at the Railway bridge it is 5 m. (c) width of river at the ocean entrance is 600 m and at the railway bridge is 100 m, respectively. [Neglect diffraction and frictional effects and approach the problem from energy considerations]
