Can Please Help Me: Waves and Optics/Physics 60 minutes only the given time. Wish you could help me. I will give UPVOTE and GOOD FEEDBACK. //Question Two adjacent point sources, A and B, are directly in front of an observer and emit identical 1000 – hertz tones. To what closest distance behind source B would source A have to be moved for the observer to hear no sound? Assume that the air temperature is 20.0°C and ignore intensity fall-off with distance. //Question
Using the table above and in the figure shown below, the transducer is stimulated with a short pulse resulting in a short burst of pressure traveling through the sequence of materials shown in figure. Assume that no echoes are returned at the transducer-tissue interface. The transducer is operating at 3 MHz frequency, measured from the transducer edge, A 3 cm and B= 5 cm. Use specific sound speeds in the corresponding materials. a) Assuming perpendicular incidence and that the system is setup to equalize the amplitude of all the returned signals (don't account for attenuation and reflection/transmittance at interfaces), sketch the timing of the first echoes (signals) received by the transducer from interfaces A, and B.
Show the appropriate figureA light is to be placed directly above the center of a circular plot of radius 30 ft,at such a height that the edge of the plot will get maximum illumination. Find theheight if the intensity I at any point on the edge is directly proportional to thecosine of the angle of incidence (angle between the ray of light and the vertical)and inversely proportional to the square of the distance from the source.

Shown below is the central part of the interference pattern for a pure wavelength of red light projected onto a double slit. The pattern is actually a combination of singleand double-slit interference. Note that the bright spots are evenly spaced. Is this a double- or single-slit characteristic? Note that some of the bright spots are dim on either side of the center. Is this a single- or double-slit characteristic? Which is smaller, the slit width or the separation between slits? Explain your responses.
Consider a spectrometer based on a diffraction grating. Construct a problem in which you calculate the distance between two wavelengths of electromagnetic radiation in your spectrometer. Among the things to be considered are the wavelengths you wish to be able to distinguish, the number of lines per meter on the diffraction grating, and the distance from the grating to the screen or detector. Discuss the practicality of the device in terms of being able to discern between wavelengths of interest.
The characters of a stadium scoreboard are formed with closely spaced lightbulbs that radiate primarily yellow light. (Use =600 nm.) How closely must the bulbs be spaced so that an observer 80 m away sees a display of continuous lines rather than the individual bulbs? Assume that the pupil of the observer’s eye has a diameter of 5.0 mm.
Determine the intensities of three interference peaks other than the central peak in the central maximum of the diffraction, if possible, when a light of wavelength 500 nm is incident normally on a double slit of width 1000 nm and separation 1500 nm. Use the intensity of the central spot to be 1mW/cm2 .
Please use neat handwriting and show work. To determine the width of a slit in a piece of paper you mount the paper a distance R = 0.6 m from a screen and illuminate it from behind with laser light of wavelengthA = 638 nm. The picture shows a distance of x = 8 mm between two of the intensity wminima. Calculate the width of the slit (in um = 10-6 m). DFoc
The transmitters emit the same 120 kHz signal as before, and the signals overlap when they reach the mobile receiver but ...After traveling an unknown distance, d1, one signal arrives at the receiver while the other bounces off a skyscraper.The signal that bounced off the skyscraper then travels an additional distance, d2, to the receiver as shown in the figure. If the signals started out in phase what minimum value of d2 gives constructive interference?
