Introduction Experiment 9 introduced us to the concept of thin lenses. We were asked to determine the focal lengths of two converging lenses and one diverging lens. The following equations were used to calculate the focal lengths: 1/p + 1/q = 1/f where p is equal to the distance of the object from the lens and q is equal to the image length from the lens‚ and f is the focal point and 1/converging F+ 1/diverging F = 1/combined. The focal point is positive for converging lenses and negative for diverging lenses

A Broad Feminist Lens of Hamlet Since medieval times‚ feminist theories have criticized English literature. Oxford professors present that the earliest forms of feminist theory can be identified in the Middle Ages‚ such as Geoffrey Chaucer’s Wife of Bath. Over the course of centuries‚ feminism has later redefined the readers’ perspectives of major literary works. Nonetheless‚ the 1960’s second wave feminism introduces modern feminist literary criticism through the inclusion of gender equality reform
