Human vision is limited to visible light wavelengths between what range, unlike Hubble's capabilities?
Answer
400 and 700 nanometers
Human visual perception is restricted to a very narrow band within the electromagnetic spectrum, specifically wavelengths roughly between 400 nanometers (which corresponds to violet/blue light) and 700 nanometers (which corresponds to red light). Astronomical phenomena often emit or reflect crucial radiation outside of this visible band, particularly in the ultraviolet (UV) and infrared (IR) regions. Hubble's cameras are specifically designed to capture these non-visible ranges, allowing scientists to observe energetic processes and structures, such as hot star formation or cool dust, that remain completely hidden to the unaided human eye.
