Answer:
Option D
Explanation:
These advancements are very expensive and not available to everyone. The others are positive aspects of these advancements in transportation.
ultraviolet rays
radio waves
infrared waves
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices, as they can penetrate and heat objects more deeply and are also emitted by objects based on their temperature.
The type of waves from the electromagnetic spectrum that are used in heat lamps and heat sensing devices are infrared waves.
These waves are invisible to the human eye but are detectable as heat. Infrared waves have longer wavelengths than visible light, which enables them to penetrate and heat objects more deeply.
For instance, a heat lamp emits infrared radiation that can warm up the objects it shines upon, while heat sensing devices, like thermal cameras, detect the infrared radiation emitted by objects based on their temperature.
