A prism will bend light towards its _______.

A prism bends light towards its base because of the way light refracts when it passes through different mediums. When light enters a prism, which is typically made of glass or another transparent material, it slows down and changes direction due to the change in density between air and the material of the prism. This bending occurs at the interfaces where the light enters and exits.

The base of the prism is the wider part and is aligned with the direction the light is being bent. As the light passes through the material and exits on the other side, it bends towards the base due to the angles formed by the entry and exit points. This principle is fundamental in optics and is utilized in various applications, such as producing rainbows, correcting vision, and in optical instruments.
