In a double slit experiment, the distance between the slits is 0.2 mm and the distance to the screen is 100 cm. What is the phase difference (in degrees) between the waves from the two slits arriving at a point 5 mm from the central maximum when the wavelength is 400 nm? (Convert your result so the angle is between 0 and 360°.) a. 90° b. 180° 270° c. d. 360° e. 160° ANS: B PTS: 3 DIF: Challenging
