Ahorizontal beam of laser light of wavelength 585 nm passes through a narrow slit that has width 0.0620 mm. the intensity of the light is measured on a vertical screen that is 2.00 m from the slit. (a) what is the minimum uncertainty in the vertical component of the momentum of each photon in the beam after the photon has passed through the slit? (b) use the result of part (a) to estimate the width of the central diffraction maximum that is observed on the screen.

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
