Flashlight Light
Why dont u see a beam of light from a flashlight refract as it travels across the room?

learning about light

The other posters are correct. I would only add that refraction is nearly the same as bending. Of course, in the case of a prism, different wavelenghts of light bend at different angles. This is known as refractive index and is the reason that prisms break visible light into the colors of the rainbow (Red, Orange, Yelloe, Green, Blue, Indigo and Violet).
