Question
Chapter 16, Problem 1DQ
To determine
The changes in the frequency, speed and wavelength of the sound when it is travels from air into water.
Expert Solution & Answer
Answer to Problem 1DQ
The frequency of sound wave doesn’t changes when it is travels from air into water. The speed of the sound changes when it travels from air into water. The wavelength of the sound changes when it travels from air into water.
Explanation of Solution
Section 1:
To determine: The changes in the frequency of the sound when it travels from air into water.
Explanation: The frequency of sound is defined as the number of vibrations that an individual particle of the source makes per unit time. The frequency of a sound wave is only depends on the source of the wave irrespective of the flowing medium. Thus, the frequency of the sound will not change when it is travels from air into water.
Therefore, the frequency of sound wave doesn’t changes when it is travels from air into water.
Section 2:
To determine: The changes in the speed of the sound when it travels from air into water.
Explanation: The speed of sound depends on the properties of the medium through which it is travels and its speed changes from medium to medium. The sound wave travels faster in medium having higher density and decreases as the density of the medium decrease. Thus, the speed of the sound will change when it is travels from air into water.
Therefore, the speed of the sound changes when it travels from air into water.
Section 3:
To determine: The changes in the wavelength of the sound when it travels from air into water.
Explanation:
Formula to calculate the wavelength of sound wave is,
From the explanation in section 1 and section 2, the frequency of the sound doesn’t changes when the sound travels from air into water, but the frequency does. Since the wavelength of the sound wave is directly proportional to the speed of the sound, so when the speed changes the wavelength will also changes. Thus, the wavelength of the sound changes when it travels from air into water.
Therefore, the wavelength of the sound changes when it travels from air into water.
Conclusion:
The frequency of sound wave doesn’t changes when it is travels from air into water. The speed of the sound changes when it travels from air into water. The wavelength of the sound changes when it travels from air into water.

Hi,
Does Quantum physics theory means all branches for example quantum relativity, Quantum mechanics, Quantum field theory, and string theory? Can you explain each one of them?

Dear Scientist in physics , How are doing, my name is Yahya from Saudi Arabia and currently in my first semester to pursue Master's degree in physics. I have been watching all interviews of some scientists in physics on YouTube Channel and somthing has got my mind. I studied my bachelor 's degree in biology and I have been contacting Professor's Bruce Lipton many times and he explained epigenatic well. He was talking about physics many times. He said if you want to understand who we are and how we think, you need to understand Physics well. So I have decided to study physics. I have some questions : Why is the community of physics are divided? What is the difference between Quantum physics, quantum field theory, Quantim theory, and classical physics? What is quantum consciousness theory as well. What do they mean by wave function collapse? Why professor Roger's always has another opinions in quantum consciousness theory??
Best Regards,
Yahya
Given water's mass of 18g/mole and the value of the fundamental charge (charge magnitude of the electron and proton), use the largest charge density from the article to determine what fraction of water molecules became ionized (charged) due to triboelectric effects when it flows through the material that causes the largest charge transfer. Give your answer in e/molecule, or electrons transferred per molecule of water. For instance, a value of 0.2 means only one in five molecules of water loses an electron, or that 0.2=20% of water molecules become charged

While walking around the fairgrounds, you discover a new game of skill. A thin rod of mass M = 0.505 kg and length = 2.70 m hangs from a friction-free pivot at its upper end as shown in the figure. Pivot Velcro M Incoming Velcro-covered ball m The front surface of the rod is covered with Velcro. You are to throw a Velcro-covered ball of mass m = 1.25 kg at the rod in an attempt to make it swing backward and rotate all the way across the top. The ball must stick to the rod at all times after striking it. If you cause the rod to rotate over the top position (that is, rotate 180° opposite of its starting position), you win a stuffed animal. Your friend volunteers to try his luck. He feels that the most torque would be applied to the rod by striking it at its lowest end.
