Infrared Waves.

Where does it appears in the EM Spectrum?

-between Microwaves and Ultra Waves.

The way of remembering all the waves in order:R – redM – menI – inV – veryU – uglyX- x-rayG – gowns

What type of wave is it?

-It is a transverse type of wave.

Can it travel through a vacuum?

Yes infrared waves are part of electromagnets radiation spectrum and all electromagnets will Propagate through a vacuum.

Frequency and wavelength around the spectrum:

sizes for wavelength are 875 nm, 880 nm, 890 nm, 940 nm and 950 nm

Examples of emitters (what does emit mean?)

An infrared emitter is a source of light energy in the infrared spectrum. It is a light emitting diode (LED) that is used in order to transmit infrared signals from a remote control.

Emit means weather to give out or send, for example “The lamp had Emitted a warm glow”

Uses/dangers of this wave:

This wave ISNOT visible however we can feel it as it is heat energy.

Its used for:- Burglar alarms- Security lights- remote controls-x-rays

Dangers: -causes skin burns - X-rays can cause damage cells

This is the experiment that we did for Infrared waves
