Final answer:
Ultraviolet radiation has shorter wavelengths compared to microwave radiation, which means it has higher frequencies and more energy.
Step-by-step explanation:
The question concerns the comparison of wavelengths between different types of electromagnetic radiation. Specifically, the query is about how the wavelengths of ultraviolet radiation compare to those of microwave radiation.
To answer this question, we need to understand that electromagnetic radiation includes a spectrum of wavelengths with different properties. In this spectrum, ultraviolet radiation indeed has shorter wavelengths than microwave radiation. This means that option (a) Ultraviolet radiation has shorter wavelengths than microwave radiation is the correct answer.
It is also worth noting that shorter wavelengths correspond to higher frequencies and typically carry more energy. Thus, ultraviolet radiation not only has shorter wavelengths compared to microwave radiation but also has higher frequencies and carries more energy.
