Simple ear-protection devices use materials that reflect or absorb sound before it reaches the ears. A newer technology, sometimes called noise cancellation, uses a microphone to produce an electrical signal that mimics the noise. The signal is modified electronically, then fed to the speakers in a pair of headphones. The speakers emit sound waves that cancel the noise. On what principle is this technology based? What kind of modification is made to the electrical signal?

Four sound waves are to be sent through the same tube of air, in the same direction:
$s_{1} (x, t) = (9.00 n m) \cos (2 π x - 700 π t)$
$s_{2} (x, t) = (9.00 n m) \cos (2 π x - 700 π t + 0.7 π)$
$s_{3} (x, t) = (9.00 n m) \cos (2 π x 700 π t + π)$
$s_{4} (x, t) = (9.00 n m) \cos (2 π x - 700 π t + 1.7 π)$
What is the amplitude of the resultant wave?

A certain microphone placed in the ocean is sensitive to sounds emitted by dolphins. Io produce a Usable signal, sound waves striking the microphone must have a decibel level of 10 dB. If dolphins emit sound waves with a power of 0.050 W, how far can a dolphin be from the microphone and still be heard? (Assume the sound waves propagate spherically, and disregard absorption of the sound waves)

B. Sound waves interfere around the comer, but light waves do not
C. Sound waves reflect around the corner, but light waves do not.
D. Sound waves refract around the corner, but light waves do not

A biologist builds a device to detect and measure the size of insects. The device emits sound waves. If an insect passes through the beam of sound waves, it produces a diffraction pattern on an array of sound detectors behind the insect What is the lowest-frequency sound that can be used to detect a fly that is about 3 mm in diameter? The speed of sound is 340 m/s.

Give three examples of mechanical waves. How are these different from electromagnetic waves, such as light waves?

The wave motion problems and solutions are often presented on various websites, yet these are not connected with the actual questions and solutions that would represent the answers. Since you can use word problems and explain the concept of wave motion, it's best when you can explore the samples that relate to college tasks. See the different types of wave motion with examples to understand how the transfer of motion happens as the energy transposes from place to place without transferring the actual matter (like how the sound waves travel in space). The basics of motion concepts will help you!
