- 3. Suppose we wish to do a double-slit experiment with a beam of smoke particles of mass 10-9 g moving at 1 cm/s. Assume we can construct a double slit whose separation is about the same size as the particles. Estimate the separation between the fringes if the double slit and the screen were on opposite coasts of the United States.#28 Monochromatic light with a wavelength of 6.4 E−7 meter passes through two narrow slits, producing an interference pattern on a screen 4.0 meters away. The first order bright band lines is 2.0 E−2 meters away from the central bright maxima.What is the distance between the slits? a 1.3 E−4 m b 8.0 E−6 m c 3.2 E−9 m d 7.8 E3 m3.Which wavelength range does the green line of the mercury lamp belong to: 600-700 nm, 500-600 nm, or 400-500 nm, or 300-400nm?
- For the machine element shown, locate the y coordinate of the center of gravity.2) Light from glowing hydrogen contains many discrete spectral lines, of which two are Ha (hydrogen-alpha) and HB (hydrogen-beta), with wavelengths of 656.3 nm and 486.1 nm, respectively. Find the first-order angular separation between these wavelengths in a spectrometer that uses a grating with 6000 slits per cm.X-rays of wavelength equal to 0.134 nm give a first order diffraction from the surface of a crystal when the value of 0(theta) is 10.5°. Calculate the distance between the planes in the crystal parallel to the surface examined. Solve correctly please full explanation needed
