Is the refraction angle smaller than the incident angle when the light in the refracted image is emitted from the air into other media?

Yes, if light enters the glass brick from air, the refraction angle is smaller than the incident angle, but if light enters the air from the glass brick, the refraction angle is larger than the incident angle, and it is concluded that the refraction angle is smaller than the incident angle when light enters the liquid or solid from gas. The angle of refraction of light from liquid or solid into gas is greater than the angle of incidence.
