Question

This part of the electromagnetic spectrum produces heat and with special equipment can locate people at night

Infrared waves
Microwaves
X-rays
Gamma waves

Answer 1

I'm guessing infrared waves, not sure tho

Answer 2

Option A, Infrared waves

Step-by-step 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.
