Answer #1

As represented by the sinusoidal curve, the pressure variation in a sound wave repeats itself in space over a specific distance. This distance is known as the wavelength of the sound, usually measured in metres and represented by ?. As the wave propagates through the air, one full wavelength takes a certain time period to pass a specific point in space; this period, represented by T, is usually measured in fractions of a second. In addition, during each one-second time interval, a certain number of wavelengths pass a point in space. Known as the frequency of the sound wave, the number of wavelengths passing per second is traditionally measured inhertz or kilohertz and is represented by f.

There is an inverse relation between a wave

Assuming two vectors are both located somewhere on the xy-plane, how could you use the right-hand rule to determine whether their cross product would point in the positive z-direction (above the plane) or the negative z-direction (below the plane)? Do not make reference to which quadrant these vectors are in, since they could be in the same quadrant or each could be in any quadrant. Consider instead the order of the vectors in the cross product.

As you sing a pure steady note of frequency 550 Hz, there is a pressure wave traveling outwards from you (at the speed of sound, naturally). What is the wavelength of that sound wave? (Assume the temperature is 20 C, room temp) Compute your answer in meters, but do not enter units to CAPA, just input the number. For you to think about: Is this a high or low note? How does that wavelength compare with ordinary sizes of things...

Someone on the deck of a pool is playing a guitar while you are underwater. How does the sound wave differ after it enters the water when you hear it as compared to the sound wave before entering the water? Include as many variables as possible in your explanation (velocity, frequency, wavelength, amplitude, energy, direction, period). Please explain fully. I am confused since I know waves move faster in a less dense medium. However, water is denser than air, but...

A kayaker paddles from the shore to out beyond the breaking surf to where the waves are sinusoidal in shape, due to simple harmonic motion. The distance between crests (peaks) are 10.0 m apart. The kayak moves a vertical distance of 1.5 m from peak to trough which takes 1.5s. Answer the following questions from this information: (a) Draw a diagram (you might need two) that demonstrates the wavelength, frequency and velocity of the wave. Make sure you show your...
