P1 - EM Receivers

HideShow resource information

Receiver size depends on wave size.

Different receivers used to pick up different types of EM waves. Includes;

  • telescopes
  • satellite dishes
  • microscopes

The longer the wavelength, the larger the receiver.

Radio waves need biggest receivers, then microwaves, then infrared, then light waves, etc.

This is due to diffraction, because when wave enters receiver, wave passes through gap. If wave is diffracted, signal/detail…
