if humans cannot see ultraviolet waves, how can ultraviolet light be used to gather evidence of a crime?\no ultraviolet light detects the presence of radioactive substances.\no ultraviolet light shows cold areas as blue and warm areas as red.\no ultraviolet light causes substances to fluoresce and give off visible light.\no ultraviolet light transmits information to am and fm radio receivers.

Answer

Brief Explanations:

Ultraviolet light can make certain substances fluoresce, emitting visible light which can be used to detect substances relevant to crime - scene investigation like bodily fluids, fingerprints etc. Radioactive substances are detected by different means (not UV light), thermal imaging shows cold and warm areas (not UV - related), and UV light doesn't transmit to AM and FM radio receivers.

Answer:

Ultraviolet light causes substances to fluoresce and give off visible light.
