Please help with question 2,3
and 4 and filling out the table
Lab 12. Sound Waves and Beats Introduction Sound waves consist of a series of air pressure variations. A Microphone diaphragm records these variations by moving in response to the pressure changes. The diaphragm motion is then converted to an electrical signal. Using a Microphone and an interface, you can explore the properties of common sounds. The first property you will measure is the period, or the time for...

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...

PLEASE ANSWERS TO ALL QUESTIONS NEEDED, THANKS Problem 13.10(a) Purpose: This is to help familiarize you with characteristics of electromagnetic waves. Problem: An electromagnetic wave travels in the z direction. The electric field in the wave is given by the expression E(z,t) = E0cos(kz-ωt)y. (Bold letter are vectors.) At z = 0 and t = 0, in what direction does the magnetic field point? Hints: Remember that E crossed into B gives the direction of travel. Enter your answer,...
