A point object O is placed on the principal axis of a convex lens of focal length 10 cm at 12 cm from the lens. When object is displaced 1 mm along the principal axis away from lens, magnitude of displacement of image is x1 .When the lens is displaced by 1 mm per...
The pump pulse is then gently focused onto the 1–5 mm BaSO4 powder that was loosely packed into a small Petri dish by using a slightly offset  3 telescope consisting of a 150-mm focal length plano-convex lens, followed by a 50-mm focal length plano-concave lens. This setup allows...
<p>To solve the problem, we will use the lens maker's formula, which relates the focal length of a lens to its refractive index and the radii of curvature of its surfaces.</p><p>1. <strong>Understanding the Lens Maker's Formula</strong>: The lens make
A plano-convex lens L1 (f = 1 00 mm) focused the three laser beams onto a light-source pinhole aperture (diameter of 20 μ m). The diffracted light was perfectly collimated using an aluminium-coated concave mirror CM (f = 1 25 mm) and was reflected using a...
