The two sources S1 and S2 shown in Fig. 35.3 emit waves of the same wavelength λ and are in phase with each other. Suppose S1 is a weaker source, so that the waves emitted by S1 have half the amplitude of the waves emitted by S2. How would this affect the positions of the antinodal lines and nodal lines? Would there be total reinforcement at points on the antinodal curves? Would there be total cancellation at points on the nodal curves? Explain your answers.

- Q35.6 The two sources S₁ and S2₂ shown in Fig. 35.3 emit waves of the same wavelength A and are in phase with each other. Suppose S₁ is a weaker source, so that the waves emitted by S₁ have half the ampli- tude of the waves emitted by S₂. How would this affect the positions of the antinodal lines and nodal lines? Would there be total reinforcement at points on the antinodal curves? Would there be total cancellation at points on the nodal curves? Explain your answers.arrow_forwardImagine that you simply compare two different water waves with unequal frequencies. If frequency of the first wave is higher than the second one, whose peak-to-peak distance is longer than the other one? Since this is just a mini-quiz,arrow_forwardThe analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation. Apply your understanding by interpreting the following statements and identifying the values of y, d, m and L. Finally, perform some conversions of the given information such that all information share the same unit. The fifth antinodal line and the second nodal line on the opposite side of an interference pattern are separated by a distance of 32.1 cm when the slits are 6.5 m from the screen. The slits are separated by 25.0 micrometers. y= ________ d=________ m=_______ L=________arrow_forward

The two waves will interfere The amplitude of the superposed wave is times A (where A is the amplitude of the original wave)arrow_forwardImagine you are in an open field where two loudspeakers are set up and connected to the same amplifier so that they emit sound waves in phase at 688 HzHz. Take the speed of sound in air to be 344 m/sm/s. What is the shortest distance d you need to walk forward to be at a point where you cannot hear the speakers? The forward direction is defined as being perpendicular to a line joining the two speakers and you start walking from the line that joins the two speakers.arrow_forwardA person in a whispering gallery standing at one focus of the ellipse can whisper and be heard by a person standing at the other focus because all the sound waves that reach the ceiling are reflected to the other person. If a whispering gallery has a length of 68 meters, and the foci are located 16 meters from the center, find the height of the ceiling at the center.arrow_forward
