In a double-slit experiment, the fifth maximum is 2.8 cm from the central maximum on a screen that is 1.5 m away from the slits. If the slits are 0.15 mm apart, what is the wavelength of the light being used?

Light with wavelength å passes through a narrow slit of width w and is seen on a screen which is located at a distance D in front of the slit. The first minimum of the diffraction pattern is at distanced from the middle of the central maximum. Calculate the wavelength of light if VAD. Give your D=1.3 m, d=1 mm and w = answer in nanometers.

Fringes in the Thomas Young experiment are produced using sodium light of wavelength 613 nm and two slits which are 1.1 mm apart. If the fringes are formed on a screen 0.9 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm).

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
