Yes, light can bend or change direction when it passes from one medium to another with a different refractive index, without changing its speed. This phenomenon is known as refraction. Refraction occurs because the speed of light changes when it enters a medium with a different optical density.
When light travels from a medium with a lower refractive index to a medium with a higher refractive index, such as from air to water or from air to glass, it slows down. As a result, the light waves change direction and bend towards the normal (an imaginary line perpendicular to the surface of the interface). Conversely, when light travels from a medium with a higher refractive index to a medium with a lower refractive index, such as from water to air or from glass to air, it speeds up, and the light waves change direction and bend away from the normal.
It's important to note that while light can change direction when it passes through different media due to refraction, its speed in a vacuum remains constant at approximately 299,792,458 meters per second. The speed of light only changes when it moves from one medium to another with a different refractive index.
