The result of a beam of light passing through a material relies entirely on the optical density of the material. If its density is lower than air, then the angle of incidence will be less (more acute) than the angle at which it enters. The opposite is true for a material with higher optical density.
less than the angle of reflection
less than the angle of refraction
greater than the angle of refraction
less than the angle of refraction.
The angle of incidence is less than the angle of refraction when a beam of light passes into a material of lower optical density. This is because light bends away from the normal when entering a less optically dense medium.
The angle of incidence is the angle at which a ray of light (which is not at right angles to a surface) strikes a surface. The angle of refraction is the angle at which a ray of light, having passed through a surface, travels through the body of a substance. Normally the angle of incidence and the angle of refraction are not the same.
When light traveling at an angle passes from one material into another, it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, due to the change in the speed of light. The degree to which the light bends depends on the angle of incidence and the refractive indices of the materials involved.
The factors that affect how light is refracted through a material include the angle at which the light enters the material, the properties of the material such as its density and refractive index, and the wavelength of the light. These factors influence the speed of light in the material, which in turn affects the bending of light as it passes from one medium to another.
The light will bend away from the normal as it enters the material where its speed is higher. This bending of light is known as refraction. The amount of bending depends on the difference in the speed of light between the two materials.
The second prism will refract the light further, altering its direction based on the prism's orientation and material properties. This refraction will depend on the angle at which the light hits the second prism and the refractive index of the prism material.

No, when light passes into a denser material, it bends toward the normal. This phenomenon is known as refraction.
