What type of optical lens is prescribed for correcting the vision defect known as Myopia (near-sight

Convex Lens (अभिसारी / उत्तल लेंस)

Concave Lens (अपसारी / अवतल लेंस)

Bifocal Lens (द्विफोकसी लेंस)

More than one of the above / उपर्युक्त में से एक से अधिक

None of the above / उपर्युक्त में से कोई नहीं

Physics: Motion, Force, Work & Light

भौतिकी: गति, बल, कार्य एवं प्रकाश

Newton's laws of motion, gravitation, work-power-energy, reflection, refraction, lenses, mirrors, and human eye.

Newton's First Law gives the definition of inertia; Second Law defines force (F = ma).
Universal Law of Gravitation: F = G(m1*m2)/r^2.
Concave mirror produces both real and virtual images; convex mirror always produces virtual, erect, diminished images.
Myopia (near-sightedness) is corrected with a concave lens; Hypermetropia is corrected with a convex lens.
