Physics Review Question Unit: Waves Year: 1990 Question#: 40 Question: A periodic wave with a frequency of 10 hertz would have a period of: (1 ) 1s (2 ) 0.1s (3 ) 10s (4 ) 100s What is this question really asking? Explanation by: Joe W. (no last names) [ Return to question menu ] Answer 1 1 s INCORRECT - because the inverse of frequency is not 15. return to top Answer 2 0.1 s CORRECT - because 10 hertz = 10/1 hz, so the period is 1/10s. f=1/T return to top Answer 3 10 s INCORRECT - because the inverse of freq. is not 10s. f=1/T return to top Answer 4 100s INCORRECT- because the inverse of freq. is not 100s. f=1/T return to top What's this question really asking? What is the inverse of 10 hertz. return to top |
