Task: Question Answering
Input (English): Background Paragraph: Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which corresponds to a frequency range between 430 and 1 THz respectively. IR wavelengths are longer than that of visible light, but shorter than that of microwaves. Infrared may be detected at a distance from the radiating objects by "feel." Infrared sensing snakes can detect and focus infrared by use of a pinhole lens in their heads, called "pits". Bright sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 53% is infrared radiation, 44% is visible light, and 3% is ultraviolet radiation. 
Story: Different wavelength electromagnetic radiations have different uses. John is a physicist. He needed to find appropriate wavelength electromagnetic radiations for his experiments. To that end, he selected three electromagnetic radiations, microwaves, infrared light, and visible light. He noted microwaves as case A, infrared as case B, and visible light as case C. 
Question: Would case C have longer or shorter wavelengths than case B?
Output (English): shorter.
