A life-guard wants your help choosing a pair of new sun-glasses to minimize reflections from the water.  She noticed an advertisement that let one choose the angle of polarization orientation of the sunglasses. What polarization angle, if any would you advise her to choose for her new glasses.   Question 6 options:   A pair of polarizing sunglasses offers no advantage for a people near the water.   Sunglasses with a horizontally oriented polarizer would be best for reducing ocean glare.   Sunglasses with a vertically oriented polarizer would be best for reducing ocean glare.
