What does Thermal Relaxation Time (TRT) measure?

Time to reach peak temperature
Time to cool down
Time to lose 50% of heat
Time to double the temperature

The correct answer is: Time to lose 50% of heat

Thermal Relaxation Time (TRT) measures the time it takes for a material to lose 50% of its acquired heat. This property is essential in laser hair removal to understand how quickly the target tissue will cool down after being heated by the laser. Options A, B, and D are not correct because they refer to different aspects of temperature change or behavior, which are not directly related to the concept of Thermal Relaxation Time.
