Light from a 580.9 nm source goes through two slits 76 micrometers apart. What is the separation of the two first order maxima occurring on a screen 1.5 m from the slits? Give your answer in mm with 3 significant figures. Light from a monochromatic source shines through a double slit onto a screen 4.7 m away. The slits are 0.15 mm apart. The dark bands on the screen are measured to be 1.7 cm apart. What is the wavelength...
