The distance between the first and fifth minima of a single-slit diffraction pattern is 0.400 mm with the screen 37.0 cm away from the slit, when light of wavelength 570 nm is used. (a) find the slit width. (b) calculate the angle θ of the first diffraction minimum.

What is created when solids,liquids,an gases mix with one another

Why can blue light and yellow light combine to produce white light? question 17 options: they are both primary colors of light. they absorb each other's wavelengths. because blue, yellow, and white are primary colors. they are complementary colors of light.

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
