When parallel light rays comes across a concave lens, the rays are refracted outwards. Concave lenses are thinner in the middle part. Parallel light rays diverge and seems to appear from one point called the principal focus. The image formed is smaller.
The light ray that pass through the lens diverge and is refracted outwards and never meets at a focal point.
Explanation:
Divergent lenses (also called concave lenses) are transparent bodies bounded by two refractory surfaces with one central axis in common. When a parallel light ray strikes a lens, it is refracted by changing its direction, this refraction in the divergent lens causes the rays to move away from the central axis, ie the ray of light passing through the lens diverges and is refracted outward. and is never at a focal point.
When Venus put in a different battery with higher voltage ... no matter what other components were in the circuit ... the voltage across the light bulb, and the current through it, both had to increase, and the light bulb had to shine brighter than before.
