- 97. ssm Mars subtends an angle of 8.0 X 10-5 rad at the unaided eye. An as- tronomical telescope has an eyepiece with a focal length of 0.032 m. When Mars is viewed using this telescope, it subtends an angle of 2.8 × 10-³ rad. Find the focal length of the telescope's objective lens.A person looking into an empty container of depth h = 16 cm can see up to a distance d = 14 cm as shown in the figure. If water is filled to a depth Y = 7 cm, what will be the new distance X to which the bottom of the container can be seen.

In addition to being effective insulators, such windows present interesting optical effects. 62.0 mm In the figure, a double-glazed window consists of two identical of glass (ng panes 1.54), each yg thick, separated by an air gap of ya = 49.6 mm. Use na = 1.00 for the index of refraction of air. = If light incident on the glass makes an angle of = 40.00° with respect to the glass, find the shift in path Ax as the light enters the room.
