• Ultraviolet light

• Infrared radiation

• X-rays

Which of the following is an advantage of using an infrared thermometer?

• It requires physical contact with the object being measured.

• It is only suitable for measuring high temperatures.

• It provides instant and non-contact temperature measurements.

• It is unaffected by the presence of reflective surfaces.

Which factor can affect the accuracy of an infrared thermometer? a) b) c) d)

• Ambient temperature

• Distance to the object being measured

• Reflective surfaces

• All of the above

How does an infrared thermometer measure temperature?

• By detecting the color of an object

• By measuring the electrical resistance of an object

• By measuring the amount of infrared radiation emitted by an object

• By analyzing the sound waves produced by an object
