Question

. Liquid crystals have wide practical application due to their optical and electrical properties.

Which of the following statements is INCORRECT about the use of liquid crystals?
A. They can be used as temperature sensors.
B. They are used in the dial of analogue watches.
C. They are used in skin thermography to detect blockage of veins.
D. They can be used to find the point of potential failure in a electrical circuits

Answer 1

C. They are used in skin thermography to detect blockage of veins.

Step-by-step explanation:

Liquid crystals are not typically used in skin thermography to detect blockage of veins. Skin thermography usually relies on infrared imaging to detect and analyze variations in skin temperature, which can indicate potential health issues. Liquid crystals are commonly used in temperature sensors, display technologies (such as in the dial of analog watches), and can be employed in electrical circuits to find potential failure points.
