Rules for obtaining images formed by convex lens
Rule 1: A ray of light which is originally parallel to the principal axis passes through the focus after refraction through the lens. Rule 2: A ray of light passing through the optical centre of the convex lens does not bent after refraction but goes straight.
Hope this much helps uh ❣️
Answer:
Rules for obtaining images formed by convex lens
Rule 1: A ray of light which is originally parallel to the principal axis passes through the focus after refraction through the lens.
Rule 2: A ray of light passing through the optical centre of the convex lens does not bent after refraction but goes straight.
Rule-3:
When a ray passes through the principal focus the refracted ray will be parallel to the principal axis.
