Consider the issue of access to public restrooms for people who are transgender. One side of the debate involves genuine safety issues for transgender individuals. For example, a person who was born with male physiology but who now identifies as female, dresses as a female, and who may have undergone hormonal and surgical treatments to become physically female, may be at risk in using a restroom designated for men only. The other side of the debate involves concerns about sharing a public restroom with a transgender individual whose sexual characteristics at birth are the opposite of those for whom the public restroom is intended. The issue is obviously very emotionally charged. As this issue continues to be discussed, what role might psychologists play in educating people about their concerns?

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina.with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
