Question 22 What occurs when this wave traveling through the rope encounters a new medium,the wall? Tie wave sHrihes the new medium and Peflecback Pnto the PopeReflectionwhen a wave encounters the boundary of a medium, it does not always transmit intoAy medium. Instead, the wave can reverse direction and travel back through theainal medium. This behavior is known as reflection. When you hear sound echo off ofuall the sound is reflecting. The wave encountered a new medium and was reflected.Partial Reflection and TransmissionWhen a wave encounters a new medium, it is normally partially transmitted and partiallyreflected. The reflected wave may flip depending on the media involved.22. How would you best describe the behavior of the wave when it reaches theboundary between the heavy particles and the light particles?Partial Transmission and Reflectiondenerally, when a mechanical wave encounters a boundary between two differentmedia, the wave is not entirely reflected or transmitted. Some of the wave can beTansmitted into the new medium, The remaining portion of the wave is reflected backto the original medium. This is why you can hear the sounds of a basketball game fromaiside a gym, even though there may be echoes inside the gym as well.Lesson 2 The Behavior of Mechanical Waves

Check Your Understanding The wave equation 2y(x,t)x2=1v22y(x,t)t2 works for any wave of the form y(x,t)=f(xvt) . In the previous section, we stated that a cosine function could also be used to model a simple harmonic mechanical wave. Check if the wave y(x,t)=0.50mcos(0.20m1x4.00s1t+10) is a solution to the wave equation. Any disturbance that complies with the wave equation can propagate as a wave moving along the x-axis with a wave speed v. It works equally well for waves on a string, sound waves, and electromagnetic waves. This equation is extremely useful. For example, it can be used to show that electromagnetic waves move at the speed of light.
A string of a constant linear mass density is held taut by two students, each holding one end. The tension in the string is constant. The students each send waves down the string by wiggling the string. (a) Is it possible for the waves to have different wave speeds? (b) Is it possible for the waves to have different frequencies? (c) Is it possible for the waves to have different wavelengths?
Waves on a swimming pool propagate at 0.750m/s. You splash the water at one end of the pool and observe the wave go to the opposite end, reflect, and return in 30.0 s. How far away is the other end of the pool?
Ultrasonic sound waves are often used in methods of nondestructive testing. For example, this method can be used to find structural faults in a steel I-beams used in building. Consider a 10.00 meter long, steel I-beam with a cross-section shown below. The weight of the I-beam is 3846.50 N. What would be the speed of sound through in the I-beam? (Ysteel=200GPa,steel=159GPa) .
The intensity of a spherical waves decreases as the wave moves away from the source. If the intensity of the wave at the source is I0, how far from the source will the intensity decrease by a factor of nine?
A 0.80-m-long tube is opened at both ends. The air temperature is 26°C. The air in the tube is oscillated using a speaker attached to a signal generator. What are the wavelengths and frequencies of first two modes of sound waves that resonate in the tube?
A trough with dimensions 10.00 meters by 0.10 meters by 0.10 meters is partially filled with water. Smallamplitude surface water waves are produced from both ends of the trough by paddles oscillating in simple harmonic motion. The height of the water waves are modeled with two sinusoidal wave equations, y1(x,t)=0.3msin(4m1x3s1t) and y2(x,t)=0.3mcos(4m1x+3s1t2) . What is the wave function of the resulting wave after the waves reach one another and before they reach the end of the trough (i.e., assume that there are only two waves in the trough and ignore reflections)? Use a spreadsheet to check your results. (Hint: Use the trig identities sin(uv)=sinucosvcosusinv and sin(uv)=sinucosvcosusinv
A 250-Hz tuning fork is struck and begins to vibrate. A sound-level meter is located 34.00 m away. It takes the sound t=0.10 s to reach the meter. The maximum displacement of the tuning fork is 1.00 mm. Write a wave function for the sound.
Many of the topics discussed in this chapter are useful beyond the topics of mechanical waves. It is hard to conceive of a mechanical wave with sharp corners, but you could encounter such a wave form in your digital electronics class, as shown below. This could be a signal from a device known as an analog to digital converter, in which a continuous voltage signal is converted into a discrete signal or a digital recording of sound. What is the result of the superposition of the two signals?
When sound passes from one medium to another where its propagation speed is different, does its frequency or wavelength change? Explain your answer briefly.
