As we have seen in class, the wavelength and frequency are inversely proportional to each other. Additionally, the wave speed is proportional to the wavelength. Thus we can express this relationship as. Remember, the frequency is the reciprocal of the period of oscillation T. In class you observed what happens to pulses and waves when they reflect off of surfaces. With the fixed end, the reflected pulses are on the opposite side of the wave.

In the activity, Paper Cup Telephone, students make telephones using cups and string. Students then modify the design of their telephones using different types of supplies to see if they can improve the sound quality. Each student will first make half of a paper cup telephone. Then, students will pair up to complete their telephones.
Addie Pillar, 25, Beaverton, Oregon. My poor brain hurts from those tasks I have in high school. How can those teachers be like slavemasters? Do they really think anyone can cope with making a working comparison between a 400-page novel and its film adaptation overnight? Ive never thought that possible but still decied to try my chances. You get my shock when I had a writer assigned for my order. I thought: the guy or gal, whoever that poor soul was, would kill him/herself while doing that. I didnt believe in miracles before, but then it was Christmas in the middle of October. I got my work done in about 60 minutes for a 2-page comparison. I didn, t put my hopes up for it when I submitted that work for grading. I got A-. All I could do was to tweak myself. Still thatA-. I aske my friend to see what grade I got. All I heard was, So, you want to boast your A-, when all class got C+ at most, yeah? Oh my, guys, you are the best. I know wholl be my best friends till I graduate college. Youre stuck with me for another five to six years.
Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations. Propagation of sound. Sound is a sequence of waves of pressure which propagates through compressible media such as air or water.
To get a deeper understanding of the process, you can explore the simulation below. The simulation above is intended to show how the process of sound wave resonance in air columns works. When a sound wave travels down an air column and reaches the other end, some of the wave reflects back.
