The E.M.S. S1 Physics Energy

Learning outcomes Success criteria Understand what a wave is in terms of energy transfer. You can define the term “wave”. Know what is meant by the “amplitude” and “wavelength” of a wave. You can draw a labelled diagram of a wave showing the amplitude and wavelength. Understand what the electromagnetic spectrum is. You can define the term “electromagnetic spectrum”. You can name at least three of the components of the electromagnetic spectrum.

All travel at the same speed. All can travel though space. Different because of their wavelengths. Which of them can we detect?

Infra-red We can’t see it But we can detect it Heat

Link

Microwaves We can’t see them

Radio Waves We can’t see them

Stars send out radio waves through space

Ultra-violet We can’t see it The following images show near ultra-violet

Ultra violet beads

X-Rays We can’t see them

True or false Light and heat travel at the same speed Ultraviolet radiation has a larger wavelength than infrared radiation Radio waves have a higher wavelength than X-rays X-rays can travel through space Microwaves have a higher frequency than light
