- Given that the wave yn = sin (2x - 50t) is superposed with the wave ym = sin (2x + 50t). Calculate The equation for the deviation of the interference results Solve max in 20 minutes thank uLet Ap be the difference between the phase shift a Helium-Neon laser beam expe- riences on traversing a given length of vacuum and on traversing the same length of plasma. What is Ad when the laser beam passes through 10 cm of plasma having a density of n = 102? m?? How could this be used as a density diagnostic? The wavelength of the He-Ne laser radiation is 632.8 nmA rocket ship floating in empty space suddenly turns on its engines and begins to rapidly accelerate toward the earth. In the first second of the acceleration, what effect would you see in the wavelength of radio signals beamed from the spacecraft back toward the earth? a) The wavelength would suddenly become shorter because the ship is now moving toward us. b) The wavelength would be unaffected because the acceleration in the first second would not yet produce a significant velocity. c) The wavelength would be longer because the transmitter is in an accelerated frame and the equivalence principle states it would slow down like a clock in a gravitational field. d) The wavelength would be shorter because the transmitter is in an accelerated frame and the equivalence principle states that it would speed up like a clock coming toward us.
- Draw a figure to show the resultant wave produced when two coherent waves (with equal amplitudes x) interact in phase. What is the amplitude of the resultant wave? If the phase difference between the coherent waves is changed to 60º, what will be new amplitude?41:24 G O O * N 5GUC I 67%, Show What You Know: Learning... KO> O 5 de 8 A new band sensation is playing a concert and recording it for a live album to be released this summer. Select all the statements that are true for when the recorded sound moves through the speaker. The frequency or amplitude of the waves will not change. The speaker changes the wave from O mechanical wave to an electromagnetic wave. The speaker changes the wave from an O electromagnetic wave to a mechanical wave. The waves from the speaker are electromagnetic waves. The frequency or amplitude of the waves could change. The waves from the speaker are mechanical waves. The speaker does not change the wave type.
