Thick lens: matrix method the matrix can be expanded 1 as 0 1 0 1 1 m = r n' r2 t 0 and the lens is surrounded by the same medium, . for a thin lens t is negligible, n n'. 1 0 1 m = r2 n 1 multiplying yields 1 1 m = ry r o ancdeskiops example 1: find the system matrix for the think lens shown below given that ri 45 cm, r2 30 cm, t = 5 cm, n, 1.6, and n = n' 1. yo

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
