if humans cannot see ultraviolet waves, how can ultraviolet light be used to gather evidence of a crime?\n○ ultraviolet light detects the presence of radioactive substances.\n○ ultraviolet light shows cold areas as blue and warm areas as red.\n○ ultraviolet light causes substances to fluoresce and give off visible light.\n○ ultraviolet light transmits information to am and fm radio receivers.

Answer

Answer:

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

Brief Explanations:

Ultraviolet light can make certain substances (like bodily - fluids, some dyes) fluoresce, emitting visible light which can be used as evidence in crime - scenes. Radioactive substances are detected by other means (not UV light). Showing cold/warm areas is an infrared property. UV light doesn't transmit to AM/FM radio receivers.
