In a double slit experiment, the distance between the slits is 0.2 mm, and the distance to the screen is 150 cm. What is the phase difference in degrees between the two waves arriving at a point P when the angular displacement of P relative to the central
maximum is 10°? The wavelength is 500 nm. (Convert your result so
the angle is between 0 - 360°).​

are there answer choices to this question? this seems like a question where you have options to choose from.
