When a monochromatic light of wavelength 433 nm incident on a double slit of slit separation 8 µm, there are 9 interference fringes in its central maximum. How many interference fringes will be in the central maximum of a light of wavelength 633.0 nm for the same double slit?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
