Solution

No ,we cannot see the wall.we cannot sense the UV light
Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 100 nm to 400 nm, shorter than that of visible light

The visible spectrum is the portion of the electromagnetric spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelength is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm
