Final answer:
The incident angle for the light ray crossing from water into glass cannot be determined as it is not provided in the question. Further information is needed.
Step-by-step explanation:
The angle of incidence for a light ray crossing from water into glass can be found using Snell's Law:
n1sin(θ1) = n2sin(θ2)
where n1 and n2 are the indices of refraction for water and glass, and θ1 and θ2 are the angles of incidence and refraction, respectively. In this case, the incident angle is not given, so we cannot determine the angle of incidence for the light ray crossing from water into glass. More information is needed.
