Interference patterns do not have an infinite number of lines, since there is a limit to how big ‘m’ can be. what is the highest order constructive interference possible if the slit width is 0.01mm and wavelength 650nm?

What is the type of the reaction below? bacl2 + h2so4 → 2 hci + baso4 double replacement synthesis single replacement decomposition

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
