Physics Review Question Unit: wave phenomena Year: 1989 Question#: 42 Question: What is the period of a wave with a frequency of 2.0 x 102 hertz? (1 ) 6.0 x 10-10 s (2 ) 2.0 x 10-3 s (3 ) 5.0 x 10-3 s (4 ) 1.5 x 106 s What is this question really asking? Explanation by: Esy C [ Return to question menu ] Answer 1 6.0 x 10-10 s INCORRECT This answer does not fit when using the formula T= 1/f. return to top Answer 2 2.0 x 10-3 s INCORRECT This answer does not fit when using the formula T= 1/f. return to top Answer 3 5.0 x 10-3 s CORRECT When using the formula T (period)= 1/ f(requency), and substituting the given frequency, this is the answer you get for period. return to top Answer 4 1.5 x 106 s INCORRECT This answer does not fit when using the formula T= 1/f. return to top What's this question really asking? Find the period of the wave with the given frequency 2.0 x 102 hertz. return to top |
