I'm guessing infrared waves, not sure tho

Answer:

Option A, Infrared waves

Explanation:

Infrared waves

Infrared radiations (IR) are the radiation that lies in the wave length range of 700 nanometers to 1 millimeter. However its frequency is the shortest

The wavelength of IR is higher than the visible light and hence it is invisible but it can be sensed as heat due to which they are used in thermal imaging and night vision equipment.  

Therefore, option A is correct.
