Final answer:
The spectrum that goes with "yay" is Microwave - Yay and the one that goes with "boo" is Ultraviolet - Boo.
Step-by-step explanation:
The spectrum that goes with "yay" is d) Microwave - Yay and the one that goes with "boo" is c) Ultraviolet - Boo.
This can be determined by considering the energy and wavelength of each spectrum. Microwaves have relatively low energy and longer wavelengths, which are less energetic than visible light. Therefore, microwaves can be associated with a less exciting or enthusiastic response like "boo". On the other hand, ultraviolet rays have higher energy and shorter wavelengths, making them more energetic than visible light. This can be associated with a more positive or enthusiastic response like "yay".
