What is the minimum thickness of a glycerin film (n = 1.47) on which light of wavelength 450 nm shines that results in constructive interference of the reflected light? assume the film is surrounded front and back by air (a)150 nm (b)76.5 nm (c)204 nm (d)102 nm

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
