Eating food during Eclipse
I heard that we ought not eat anything in eclipse hours. Is there any scientific reason for that?
Tejaswini asked
Answer:
There is no scientific reason behind it. Earlier it was thought that more harmful rays are reaching earth from sun at the time of eclipse. But actually it is less at the time of eclipse as they are blocked by moon coming in its path.

Electricfield, Magnetic Field and Photon
We know that photon has no charge. Then where from it gets electric and magnetic field in light? Malik Sajad asks Answer: Electric and magnetic fields are not produced by the photon; it is massless too. But, photon is created by time varying electric a...
