You want to photograph a circular diffraction pattern whose central maximum has a diameter of 1.3 cm . You have a helium-neon laser (λ=633nm) and a 0.16-mm-diameter pinhole. How far behind the pinhole should you place the viewing screen? Express your answer to two significant figures and include the appropriate units.
please answer the following questions 3. Many cell phones broadcast their signals at 800 MHz. Imagine you are behind 2 large, radio-wave-absorbing building with only a 13 m space between them. What is the angular distance, in degrees, of the radio wave after it emerges from between the buildings? 4. You want to recreate the circular diffraction pattern you saw in lab to show some friends. You borrowed a helium-neon laser (lambda = 633 nm) and made a 0.15 mm...
Suppose you want to produce a diffraction pattern with X-rays whose wavelength is 0.030 nm . Part A If you use a diffraction grating, what separation between lines is needed to generate a pattern with the first maximum at an angle of 15 ∘ ? (For comparison, a typical atom is a few tenths of a nanometer in diameter.) ??? nm
Laser light of wavelength 480 nm is incident on a circular aperture which has a diameter of 0.011 mm. A diffraction pattern is observed on a screen which is placed 94 cm from the aperture. Give your answer to at least three significant figures. Answer must be accurate to 1%. diffraction angle, θ, of the first diffraction minimum: 3.051662 degrees You are correct. 1) What is the distance, on the screen, from the center of the central bright spot to the...
When laser light of wavelength 632.8 nm passes through a diffraction grating, the first bright spots occur at ± 17.0 ∘ from the central maximum. How many additional pairs of bright spots are there beyond the first bright spots? A converging lens 6.90 cm in diameter has a focal length of 310 mm If the resolution is diffraction limited, how far away can an object be if points on it transversely 4.00 mm apart are to be resolved (according to...
) In the figure, a slit 0.30 mm wide is illuminated by light of wavelength 426 nm. A diffraction attern is seen on a screen 2.8 m from the slit. What is the linear distance on the screen between e first diffraction minima on either side of the central diffraction maximum? Answer: 8.0 mm 30) A thin beam of laser light of wavelength 514 nm passes through a diffraction grating having 3952 lines/cm. The resulting pattern is viewed on a...
I have the answers but need to see these worked out. Thanks! 11- The nickel's image in the figure has twice the diameter of the nickel when the lens is 2.84 cm from the nickel. Determine the focal length of the lens. 12- Problem 22.17: An electric catfish can generate a significant potential difference using stacks of special cells called electrocytes. Each electrocyte develops a potential difference of 110 mV. How many cells must be connected in series to give...
