Final answer:
The angle of refraction can be found using Snell's Law, while the speed of light in water can be calculated using the equation v = c/n.
Step-by-step explanation:
When a light ray travels from glass into water, the angle of refraction in the water can be determined using Snell's Law: n1sin(θ1) = n2sin(θ2). In this case, the angle of incidence in glass is 30.0° and the refractive indices of glass and water are known values. By plugging in these values, we can solve for the angle of refraction in water.
The speed of light in water can be calculated using the equation: v = c/n, where v is the speed of light in a medium, c is the speed of light in vacuum or air, and n is the refractive index of the medium. By substituting the appropriate values, we can determine the speed of light in water.
