Answer 1

The correct answer is 45°.Key Points

The incident angle in air is 60 degrees.
The refractive index of the medium is\(\sqrt{(3/2)}\).
Using Snell's law, we can calculate the angle of refraction in the medium.
The angle of refraction is 45 degrees.

Additional Information

The angle of refraction is always less than the angle of incidence when light travels from a rarer to a denser medium.
The angle of refraction cannot be less than the critical angle, which is the angle of incidence that produces an angle of refraction of 90 degrees.
Refractive index is a measure of how much a material bends light as it passes through it.
The refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in that medium.
The refractive index of a medium depends on the wavelength of light.
The refractive index of a medium determines the amount of refraction that occurs when light passes from one medium to another.
