Final answer:
The most appropriate use of the photon from Part C would be in night-vision goggles, which use infrared technology to see in the dark.
Step-by-step explanation:
The photon from Part C would be most useful for night-vision goggles. This is because, based on the preceding context and given the options, the infrared photons can be detected in the dark, and night-vision goggles typically use infrared technology to amplify available light to make it possible to see in very low-light conditions. Warming up a frozen hot dog would require infrared radiation too, but it is more commonly done with a microwave or conventional oven.
For checking for broken bones, X-ray photons are typically used, not infrared photons. Getting a suntan would require UV rays rather than infrared photons. Listening to music involves sound waves, which are not part of the electromagnetic spectrum and definitely not related to photon usage. Finally, in terms of practical everyday use, infrared photons are most commonly associated with heat sensing and imaging in low-light conditions, making them ideal for night-vision applications.
