A is for atoms - Frank Close 1993 Christmas Lectures 1/5

In his first lecture, Frank Close takes a look at the electromagnetic spectrum beyond the rainbow, from infrared to ultraviolet, from radio waves to gamma waves. This was recorded on 1 Dec 1993. Our five senses only reveal a small part of the large variety in the Universe. We cannot see molecules unaided (though our nose can smell particles much smaller than our eyes can see) and we only respond to the rainbow of colours – a mere octave in the infinite range of the electromagnetic spectrum.
