In a two-slit experiment, the slit separation is 6.50 × 10-5 m. the interference pattern is created on a screen that is 1.60 m away from the slits. if the 6th bright fringe on the screen is 8.00 cm away from the central fringe, what is the wavelength of the light?

What is the length x of the side of the triangle below? (hint: use the cosine function)

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
