2/20/24, 8:34 AM W7a: Pre-Lab Quizzes (2 attempts): 3LB: Basic Physics Lab II https://canvas.eee.uci.edu/courses/61657/quizzes/315035 1/2 W7a: Pre-Lab Quizzes (2 attempts) Due Feb 23 at 11:59am Points 2 Questions 2 Available Feb 20 at 8am - Mar 14 at 11:59pm Time Limit None Allowed Attempts 2 Instructions Attempt History Attempt Time Score LATEST Attempt 1 3 minutes 2 out of 2 Score for this attempt: 2 out of 2 Submitted Feb 20 at 8:34am This attempt took 3 minutes. Question 1 1 / 1 pts None of the other choices The frequency that sounds the loudest Correct! The frequency of maximum energy transfer to the system The frequency range over which a detector is considered "good" The weekly pre-lab is due before the beginning of your Lab session. The problem sets will be open for one week prior to the due date. Any technical problems with the website (e.g. trouble logging on) should be reported to the OIT Help Desk staff. (https://www.oit.uci.edu/helpdesk/) If you have questions about grading or mistakes in the quiz, contact your Instructor and/or TAs. NOTE: In this Quiz, you will have TWO Attempts. Take the Quiz Again Resonant frequency problem. What is the definition of 'resonant frequency'?

A 30 kHz sine wave No response Quiz Score: 2 out of 2 Harmonics problem. A square wave of frequency f contains harmonics (sine waves) at f, 3f, 5f, 7f, ... .Suppose a system responds to frequencies in the range 20-40 kHz but is insensitive outside of this range. EXAMPLE: Imagine applying a square wave with f = 30 kHz to this system. What is the shape of the response? [Answer: a 30 kHz sine wave. ] QUESTION: Imagine applying a square wave with f = 10 kHz to this system. What is the shape of the response?
