Physics 41- Lab 5 Determination of Focal Length of A Converging Lens and Mirror Objective: Apply the thin-lens equation and the mirror equation to determine the focal length of a converging (biconvex) lens and mirror. Apparatus: Biconvex glass lens, spherical concave mirror, meter ruler, ...
Convex and concave mirrors are sections of a whole spherical mirror. A concave mirror has a reflecting surface on the inner part of the mirror. Its center of curvature and focal point is located on the same side as the object, making its focal length positive. On the other hand, a conve...
This study aims to investigate the frequency-dependent characteristics of the focal length of an acoustic lens made of a material with a frequency-dependent acoustic refractive index (ARI). For this purpose, an exchangeable plano-spherical convex subsonic index lens (PSCSIL) was fabricated using a...
