The hydrogen spectrum has a red line at 656 nm and a violet line at 434 nm. What angular separation between these two spectral lines is obtained with a diffraction grating that has 4324 lines/cm? (Assume that the light is incident normally on the grating.) first order separation second order separation third order separation

You measure three segments of the distance between a diffraction slit an the screen on which the pattern forms: x1 = (15.8 ± 0.2) cm, x2 = (6.7 ± 0.1) cm, and x3 = (11.3 ± 0.1). What is the uncertainty of the total distance x1 + x2 + x3? Group of answer choices 0.4 cm 0.5 cm 0.2 cm 0.3 cm 0.1 cm

Light from an argon laser strikes a diffraction grating that has 4,300 grooves per centimeter. The central and first-order principal maxima are separated by 0.444 m on a wall 1.67 m from the grating. Determine the wavelength of the laser light. 597.5 nm 510.7 nm 440.3 nm 363.9 nm

Narrow, equally spaced vertical slits with equal widths are located at a distance of D = 2.47 m from a screen. The intensity pattern in the figure is observed when light with wavelength = 570 nm from a laser passes through the slits, illuminating them uniformly. The screen is perpendicular to the laser beam. 0 1 2 3 4 5 6 7 8 9 cm 7 The number of slits is ... Submit Answer Incorrect. Tries 1/3 Previous Tries Calculate the center to center spacing between the slits. Use the cm scale to measure distances on the screen. 2.25x10^-6 cm There is a fixed relation between wavelength, slit separation, and angle between the first (or second, third etc) order maximum and the central maximum. The angle can be determined from the distance to the screen and the separation between the first maximum and the central maximum on the screen. Submit Answer Incorrect. Tries 1/12 Previous Tries Calculate the width of the slits. Use the cm scale to measure distances on the screen. Submit Answer Tries 0/12

A nearly monochromatic beam of light with an average wavelength of 516 nm is incident normally on a diffraction grating 2.90 cm wide with 1300 lines/cm. What is the smallest wavelength difference (in nm) this grating can resolve in the second order diffraction with this beam?Type your answer here

A blackbody radiator in the shape of a sphere has a surface area of 152 If it has a temperature of 1200 K how much energy does it emit per second? If the sun emits light with a peak wavelength of 500 nm. What is the temperature of the sun? Two slits, 0.5 mm apart, are placed at a distance of 1.5 meters from a screen. Light of 300 nm illuminates the two slits and an interference pattern is observed on the screen.  What is the distance between the central bright spot and the first bright spot on either side?
