(iv) The power of a convex lens increases when the lens is cut into two identical plano-convex lenses.

<h3>What is power of a lens?</h3>

The power of a lens is defined as the reciprocal of its focal length. It is measured in diopters.

<h3>Factors affecting the power of a lens</h3>

The power of a lens depends on the focal length of the lens which depends on;

  • the refractive index of the glass from which it is made, and
  • on the curvature of its two surfaces

P = 1/f

where;

  • P is power of the lens
  • f is focal length of the lens

When the focal length decreases, the power of the lens increases.

Thus, the power of a convex lens increases when the lens is cut into two identical plano-convex lenses.

What is happening inside muscles when they become sore?
Verizon [17]

Answer:

When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness. DOMS is often mistakenly believed to be caused by a build up of lactic acid, but lactic acid isn't involved in this process.
