what makes thermal imaging cameras useful?\no they can detect differences in color.\no they can detect differences in wave speeds.\no they can detect differences in temperature.\no they can detect mechanical waves.
Answer
Brief Explanations:
Thermal imaging cameras work by detecting infrared radiation which is related to temperature differences. They don't detect color differences, wave - speed differences or mechanical waves in the context of their main function.
Answer:
They can detect differences in temperature.
