b. 53.1°
c. 77.3°
d. 48.8°
e. 45.0° A child is looking at a reflection of the sun in a pool ofwater. When she puts on a pair of Polaroid sunglasses with avertical transmission axis, she can no longer see the reflection.At what angle is she looking at the pool of water? 61.6° 53.1° 77.3° 48.8° 45.0°

Explanation / Answer

The required angle be angle of polarization we know angle of polarization P = tan -1 ( n) where n = indexof refraction of water = 4 / 3 So, P = 53.13 degrees
