Po Ka Ep! A minion 18.0 [cm] tall is standing 320.0 [mm] from a thin lens. The lens forms the minion’s image at 70.0 [mm] on the same side as the minion itself. What is the focal length magnitude of this lens, and what is its type?

Physics 72 beach episode. A sea star at the bottom of a clear, shallow sea ( 1.33) appears to be 5.5 [ft] deep. What is its actual depth?

Christmas ka ba? Kasi I wanna merry you. A Christmas globe with radius 5.00 [cm] and made of glass with refractive index 1.57 has a small Christmas tree inside it, located 2.00 [cm] from the globe's surface. What is the apparent distance of the Christmas tree when viewed from the right side of the globe?

Lamok ka ba? Kasi mis-na-quita. A Jurassic mosquito is discovered embedded in a chunk of amber ( = 1.60). One surface of the amber is spherically concave with respect to the observer, with a radius of curvature of 4.00 [cm] (see figure). The mosquito head appears to be buried at 4.00 [cm] from from the air-amber interface. Where is the actual location of the mosquito head with respect to the interface?
