.A first order bight line is 18cm from the central bright line. The distance from the center of the slits to the first order line is found to be 62.0 cm. If the slits were .0000019m apart. What was the wavelength of the light? What color was the light?

A diffraction grating is illuminated by light of wavelength 4.50 nm. The first order line is 0.50 m from the central bright line, the distance from the center of the slits to the first order dark band is 2.0 m. How many lines are there per centimeter in the grating?

Light of frequency 5.0 x 10 (e 14) Hz illuminates two slits that are .0002m apart. How far from the central bright spot is the first order bright line on a screen 1.5 m from the slits?

Light of frequency 7.5 x 10(e 14) Hz falls on a slit .00015 m wide and produces a first order dark band at 0.65 cm from the center of the central bright band. What is the distance of the screen from the slit?

Please show all work and equations used. Thanks

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
