Why does the ray of light passing through the optical Centre of a lens not get any deviation?
Why does the ray of light passing through the optical Centre of a lens not get any deviation? The ray passing through optical center does no deviate because the curvature of the Lens at the incident and exit point are exactly opposite so the deviation at the first point is cancelled at the other point. […]

What is the main reason for acid mine drainage?
What is the main reason for acid mine drainage? Acid mine drainage (AMD) is the runoff produced when water comes in contact with exposed rocks containing sulfur-bearing minerals that react with water and air to form sulfuric acid and dissolved iron. This acidic run-off dissolves heavy metals including copper, lead, and mercury which pollute ground […]
How does the body convert starch to glucose?
