Yes, as electromagnetic radiation moves from the visible spectrum to the infrared, ultraviolet, and X-ray regions, the wavelengths do change. Each region of the electromagnetic spectrum corresponds to a specific range of wavelengths and frequencies.
In the visible spectrum, different wavelengths of light are associated with different colors. The wavelength range for visible light is approximately 400 to 700 nanometers (nm), with violet light having the shortest wavelength and red light having the longest wavelength.
Moving beyond the visible spectrum, as we transition into the infrared region, the wavelengths become longer than those of red light, typically ranging from about 700 nm to 1 millimeter (mm).
In the ultraviolet (UV) region, the wavelengths become shorter than those of violet light, typically ranging from about 10 nm to 400 nm.
Finally, in the X-ray region, the wavelengths become even shorter, typically less than 10 nanometers and can extend down to picometers (10^-12 meters) or even smaller.
It's important to note that the exact boundaries between these regions may vary slightly depending on the context and conventions used, but the general trend of shorter wavelengths as we move from visible to infrared, ultraviolet, and X-rays holds true.
