(40%) Each question is worth 5%. In the space provided, to the left of the question number, write the letter corresponding to the best answer to the question. ___ 1. When standing waves are set up in a string that is fixed at both ends, the only frequencies that the waves can have are given by the equation, f = nf , where f is the fundamental frequency of the string, and n is an integer. If a standing wave is established in a string that is 6.0 m in length, with a wavelength of 3.0 m, what is the value of n ? A. 1 B. 2 C. 3 D. 4 E. some other integer. ___ 2. A source of electromagnetic waves emits waves uniformly in all directions. The amplitude of the electric field of the waves is E at a distance of r from the source. At a distance of 2 r from the source, the amplitude of the electric field of the waves will be: A....
