Which type of waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices? visible light
ultraviolet rays
radio waves
infrared waves

Answers

Infrared waves are used in heat lamps and other heat sensing devices. Infrared waves or commonly known as Infrared radiations (IR) is the type of electromagnetic radiation we encounter most in our everyday life. Heat lamps are electrical devices which emit infrared radiation.

Final answer:

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.

Explanation:

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.
