Final answer:
The electromagnetic radiation with a frequency of 0.705 × 10¹⁷ Hz falls within the range of ultraviolet radiation.
Step-by-step explanation:
The type of electromagnetic radiation with a frequency of 0.705 × 10¹⁷ Hz can be identified by comparing it to the ranges of frequencies that correspond to different types of EM radiation. The electromagnetic spectrum includes, in order of increasing frequency: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Infrared radiation typically has frequencies from about 3 × 10¹¹± Hz to 4.3 × 10¹⁴ Hz,
visible light from about 4.3 × 10¹⁴ Hz to 7.5 × 10¹⁴ Hz,
ultraviolet radiation from about 7.5 × 10¹⁴ Hz to 3 × 10¹⁷ Hz, and
X-rays from about 3 × 10¹⁷ Hz to 3 × 10¹⁹ Hz.
The given frequency of 0.705 × 10¹⁷ Hz falls within the classification of ultraviolet radiation.
