An explorer is riding his camel in the desert. Up ahead he sees what appears to be a pool of water.
He can tell if it is a real pool of water or a mirage by putting on his polarized sun glasses because:
a) The mirage is polarized and reflections from the water are not
b) Reflections from water are polarized while the mirage is not
c) Neither are polarized so one will not be able to discern a difference
d) Both are polarized so one will not be able to discern a difference
Ans- Reflections from water are polarized while the mirage s not
plz derive a equation to magnetic force between short magnetic dipoles at distance apart?
Q. An aircraft having awing span of 10 m flies at a speed of 720 kmph. If the vertical component of the earth's magnetic field is 3 X 10 -5 T, calculate the emf induced between th
Refracting telescopes, if uncorrected, suffer from chromatic aberration. Chromatic aberration occurs because: a) red light is focused more strongly than blue light b)
Production of a magnet: Magnets can be produced in a variety of ways, generally the method used is determined by the type of magnet required. Using the stroke method
