Express your answer in meters to three significant figures.View Available Hint(s)**Answer Box:**\[ r_1 = \_\_\_\_\_\_\_\, \text{m} \]---**Explanation:**1. **Part C:** This part asks to find the speed of sound waves in air. The speed is given as 351 m/s with three significant figures. 2. **Part D:** This part demands the calculation of the necessary distance \( r_1 \) that the speaker should be moved to achieve constructive interference for the second time. The answer should be submitted in meters to three significant figures. There are interactive tools such as hints available to aid in solving the problem. ### Sound Wave Interference from LoudspeakersTwo loudspeakers are placed side by side a distance \( d = 4.00 \, \text{m} \) apart. A listener observes maximum constructive interference while standing in front of the loudspeakers, equidistant from both of them. The distance from the listener to the point halfway between the speakers is \( L = 5.00 \, \text{m} \).One of the loudspeakers is then moved directly away from the other. Once the speaker is moved a distance \( r = 60.0 \, \text{cm} \) from its original position, the listener, who is not moving, observes destructive interference for the first time.Find the speed of sound \( v \) in the air if both speakers emit a tone of frequency \( 700 \, \text{Hz} \).#### Figure Explanation:The figure displays the arrangement of the two loudspeakers and the listener. The following points describe the layout:- **Two Loudspeakers**: The leftmost points represent the two loudspeakers which are initially \( d = 4.00 \) meters apart.- **Listener**: The listener is depicted on the right side of the diagram.- **Distances**: - \( d/2 \): Half the distance between the loudspeakers. - \( L \): The horizontal distance from the midway point between the speakers to the listener which is \( 5.00 \, \text{m} \). - \( r \): The new position of one loudspeaker which is \( 60.0 \, \text{cm} \) away from its initial point directly to the left.- **Path Difference**: - \( r_1 \): The distance from one speaker to the listener. - \( r_2 \): The distance from the moved speaker to the listener.The figure is essential to understanding the path difference created by the movement of one of the speakers, leading to destructive interference at the listener's position.### Calculation Steps:1. **Constructive Interference Condition**: Initially, with both speakers fixed, the path difference is zero at the listener's position, resulting in constructive interference.2. **Destructive Interference Condition**: When one speaker is moved \( r \), the path difference must be equal to half of the wavelength \( \lambda /2 \

Intendiinia Introduction to Oceanography Figure 3 An echo sounder determines water depth by measuring the time required for an acoustic signal to travel from a ship to the seafloor and back. The speed of sound in seawater is 1500 m/sec. th's with the invention of electronic depth-sounding equipment. The echo sounder (also referred to as sonar) measures the precise time that a sound wave, traveling at about 1500 meters per second, takes to reach the ocean floor and return to the instrument (Figure 3). Ships generally don't make single depth soundings. Rather, as a ship moves from one location to another, it continually sends out sound pulses and records the returning echoes. In this way, oceanographers obtain many depth recordings from which a profile (cross-sectional view) of the ocean floor can be prepared. Today, in addition to using sophisticated echo sounders such as multibeam sonar, oceanographers are also using satellites to map the ocean floor. Outgoing signal Reflected signal…
