The electromagnetic spectrum spans from radio waves to gamma rays. The picture provided illustrates this entire spectrum. However, the optical telescope is limited to observing only the visible spectrum, which ranges from 400 nm to 700 nm. This segment reflects the colors of ROYGBIV, with red exhibiting the highest frequency and violet the lowest frequency.

Answer:

Ultraviolet and Infrared

Explanation:

The electromagnetic spectrum includes all kinds of electromagnetic waves categorized by their frequencies and wavelengths. It comprises waves from radio frequencies, which are the lowest, to gamma rays, which have the highest frequencies. An optical telescope allows Mike to see only the visible portion of this spectrum, representing merely 7% of its entirety.

Ultraviolet (UV) and Infrared (IR) rays are closest to the frequency range of visible light. UV rays have a frequency that is higher than visible light, while IR rays have a frequency that is lower.
