- Sound Wave Interference Revisited Draw two harmonic waves that are 90 out of phase. Then draw the superposition of these two waves.arrow_forwardIs light a transverse or a longitudinal wave? Explain?arrow_forwardhigh-frequency sound waves exhibit less diffraction than low-frequency sound waves do. However, even high frequency sound waves exhibit much more diffraction under normal circumstances than do light waves that pass through the same opening. The highest frequency that a healthy ear can typically hear is 2.0 × 104 Hz. Assume that a sound wave with this frequency travels at 344 m/s and passes through a doorway that has a width of 0.95 m. (a) Determine the angle that locates the first minimum to either side of the central maximum in the diffraction pattern for the sound. (b) Suppose that yellow light (wavelength = 567 nm, in vacuum) passes through a doorway and that the first dark fringe in its diffraction pattern is located at the angle determined in part (a). How wide would this hypothetical doorway have to be?arrow_forward

Calculate the frequency of the 7’th harmonic. (2) A thin converging lens has a focal length of 100mm. An object is placed 150 mm in front of the lens. Calculate the image distance and the magnification. Is the image virtual or real, erect or inverted? (3) A generator rotates such that the flux changes from -10,000V-s to 10,000Vs every 0.005s. Calculate the voltage difference generated.

Ocean waves of 43.0 m wavelength approach the opening straight on. At what angle (in degrees) to the incident direction are the boats inside the harbor most protected against wave action?arrow_forwardIn large auditoria, where even sound coverage and speech intelligibility is important:a. concave, reflective surfaces are usually useful because they can focus reflections and increase the level of direct sound at certain listener locationsb. concave, reflective surfaces are usually problematic because they can focus reflections at certain listener locationsc. it is usually best to make the rear wall of a material that is acoustically reflective because it can provide useful reflections to people sitting near the backd. it is usually best to provide as much sound absorbing material as possiblearrow_forward
- A light ray in air enters and passes through a block of glass, where the speed of light is less than in air. What can be stated with regard to speed of the wave after it emerges from the block back into air? Explain. Does this violate conservation of energy?arrow_forwardIntegrated Concepts A water break at the entrance to a harbor consists of a rock barrier with a 50.0-m-wide opening. Ocean waves of 20.0-m wavelength approach the opening straight on. At what angle to the incident direction are the boats inside the harbor most protected against wave action?arrow_forwardWhen dots are placed on a page from a laser printer, they must be close enough so that you do not see the individual dots of ink. To do this, the separation of the dots must be less than Raleigh's criterion. Take the pupil of the eye to be 3.0 mm and the distance from the paper to the eye of 35 cm; find the minimum separation of two dots such that they cannot be resolved.

Outside the door, on a line perpendicular to the opening in the door, a jet engine makes a 600-Hz sound. At what angle with the door will the technician observe the first minimum in sound intensity if the vertical opening is 0.800 m wide and the speed of sound is 340 m/s?arrow_forwardA student holds a laser that emits light of wavelength . The laser beam passes through a pair of slits separated by a distance d, in a glass plate attached to the front of the laser. The beam then falls perpendicularly on a screen, creating an interference pattern on it. The student begins to walk directly toward the screen at speed v. The central maximum on the screen is stationary. Find the speed of the mth-order maxima on the screen, where m can be very large.arrow_forward
