Can I separate UV/IR from sunlight with a prism?

If a prism separates all wavelengths from a light source, does this mean that the UV and IR component of sunlight is separated as well? When sunlight is passed through a prism, is UV concentrated next to violet and IR next to red?

Yes, and that was in fact how IR was discovered. Sir Frederick William Herschel did an experiment where put thermometers in the different colors of light separated through a prism. He found that the temperatures increased when going from blue to red, so he put a thermometer right next to the red light, and found that it showed an even hotter temperature than the thermometer in the red light.
