Using moonlight to start fires...
« on: 02/11/2011 23:01:02 »
Slava Vitsev  asked the Naked Scientists:
   
I think your site is the best among the scientific and errors are very rare. But I think that in a podcast on October 23, 2011 there is an error in the answer to the question: Can we use moonlight to start a fire?

Moonlight is not a black-body radiation. It is the light of the sun reaches us reflected from the moon likely as from a mirror.  Visible light has a frequency range with an energy of about 0.5 eV, which is equal to a temperature of about 5000 degrees. Therefore a large telescope would be able to burn the paper.

Kind regards,

Slava Vitsev
