Answer:
53.06°
Explanation:
refractive index of air = 1
refractive index of water, n = 1.33
Let the angle of polarisation is ip.
Use Brewster's law,
n = tan ip
1.33 = tan ip
ip = 53.06°
thus, the angle of polarisation is 53.06°.
Answer: 10m per second.
Explanation: 100/10 is 10/1, so it would be 10m per second.
