In a certain two slit diffraction experiment, two slits 0.02mm wide are spaced0.2mm between centers.(a) how many fringes appear between the first minima of the single slit envelopeon either side of the central maximum? (b) if the angle between the central maximum and the second fringe to eitherside of the central maximum is 0.17 degrees, what is the wavelength?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?

Which of the following conditions lead you to see an absorption line spectrum from a cloud of gas in interstellar space? the cloud is extremely hot. the cloud is visible primarily because it reflects light from nearby stars. the cloud is cool and lies between you and a hot star. the cloud is cool and very dense, so that you cannot see any objects that lie behind it.
