Some parameters which all traveling waves have include its wavelength (lambda), period T, wave speed v, amplitude ym, etc. ATTACHMENT #1 is a diagram of a typical wave, a sine curve, with points A, B, etc. identifying various points and lengths of a wave.
PART a. On ATTACHMENT #1, in the spaces shown after the parameters listed, write in the letter(s) which that parameter describes. Then see ATTACHMENT #2 to check your work for correct answers and see explanations in the posted solution.
PART b. For a movingsound wave, with frequency is 440 cy/sec, traveling at velocity 346 m/sec, find the wave length of the sound.
PART c. For a moving wave on the surface of the sea, if 12 crests move past a point in 24 seconds (counting 0 for the first one), moving at 3 m/sec, find the wavelength of the wave.

PART a.
The identified parts of a wave must show that the wavelength is the distance from one crest to the next, or one trough to the next, etc.
The amplitude is the maximum value of y.
Points on a ...

Solution Summary

Wave problems are emphasized. The spaces shown for the wavelength parameters are given.

Identify the following types of waves as electromagnetic (EM) or sound waves. Briefly justify your choice.
1. Waves that enable you to feel that a campfire is hot from 2 feet away.
2. Waves in your microwave oven that enable you to heat food.
3. Waves that come out of the speaker in your cell phone.
4. Waves that reach you

Waves on a particular string travels with a speed of 16 m/s. By what factor should the tension in this string be changed to produce waves with a speed of 32 m/s?

Please answer all questions with full explanations
1) An ultrasound wave has frequency 100 kHz and wavelength (in air) of 3.5mm. What is the speed of these ultrasonic waves?
2) 3mm wavelength radar waves have speed 3.00 x 10(8) ms(-1) (as do all electromagnetic waves in air) what is their frequency?
3) Ultrasound is a l

In some media, waves of different frequencies travel at different speeds. Such a medium is called a dispersive medium because waves that are not sinusoidal will change shape or disperse over time.
For example, a superposition of two such waves of different frequencies is described by the e

1. Organ pipe A, with both ends open, has a fundamental frequency of 300 Hz. The third harmonic of organ pipe B, with one end open, has the same frequency as the second harmonic of pipe A. How long are (a) pipe A and (b) pipe B?
2. A tuning fork of unknown frequency makes 3.00 beats per second with a standard fork of frequenc

Energy released by an earthquake is transmitted to other parts of Earth in the form of seismic waves. What are the two types of waves that are produced during an earthquake? How do scientists use waves to locate the epicenter of the earthquake and to tell about our earths interior? Please help and advise references.

Assume that the phase velocity of waves in some dispersive medium is given as a function of wave length lamda by the relationship
see attached
Express the group velocity in terms of lamda, v_0 and lamda_0.

Please answer the following:
1. How does wave amplitude change as waves propagate outward?
2. How does the resultant wave's wavelength change if we introduce two waves? Do you encounter similar effects in daily life?
