Visible light has a frequency of approximately $5.0 \times 10^{14}\,\text{Hz}$. M and N are two other forms of electromagnetic radiation. M has a frequency of $5.0 \times 10^{6}\,\text{Hz}$. N has a frequency of $5.0 \times 10^{15}\,\text{Hz}$. What are the types of radiation for M and N?
- AM: radio waves, N: infrared
- BM: radio waves, N: ultraviolet
- CM: ultraviolet, N: X-rays
- DM: X-rays, N: infrared
