Light with a wavelength of 750nm shines normally on a double slit. The fourth order (m=4) bright fringe is observed at an angle of 1.5 degrees. What is the distance between the slits? At what angle will the first order (m = 1) bright fringe be observed?

An optical engineer needs to ensure that the bright fringes from a double-slit are 15.7 mm apart on a detector/ screen that is 1.20 m from the slits. If the slits are illuminated with 633 nm light, how far apart should the slits be? 48.4 μm 74.0 μm 49.5 μm 36.0 μm 8.28 nm   A horizontally polarized beam of light of intensity 100 W/m2 passes through a polarizer with its transmission axis at 40.0° with the vertical. What is the transmitted intensity of this beam of light? 0 W/m2 50 W/m2 64.3 W/m2 58.7 W/m2 41.3 W/m2 Correct answers are underlined can you help explain?

A transmission grating has 2550 lines/cm. Consider a beam of monochromatic light normal to the surface. It is found that the angle of the first-order bright fringe is 10 degrees. What is the wavelength of the light? (in nm) OA: 681.0 OB: 796.7 OC: 932.2 OD: 1090.7 OE: 1276.1 OF: 1493.0 OG: 1746.8 OH: 2043.8

In a double-slit interference experiment, the wavelength is 737 nm, the slit separation is 0.180 mm, and the screen is 33.0 cm away from the slits.  What is the linear distance between the sixth order maximum and the third order maximum on the screen in millimeters?
