It's nighttime, and you've dropped your goggles into a 3.65 m deep swimming pool. If you hold a laser pointer 1.48 m above the edge of the pool, you can illuminate the goggles if the laser beam enters the water 1.57 m from the edge. How far are the goggles from the edge of the pool? n of water is 1.33. A 2.50-cm-tall candle flame is 4.40 m from a wall. You happen to have a lens with a focal length of 20.0 cm, and notice while playing around with it that there are two locations you can place the lens and form a well-focused image of the candle flame on the wall. What is the distance between these two lens locations? :1 A slab of glass has a 0.900 cm thick layer of water on top of it. A light ray strikes the water from air at an incident angle of 63.0. At what angle does the light ray travel through the glass? Angle: W At what angle does the laser beam need to be at to hit the mirror then hit the midpoint of the wall? The height of the room is h = 3.30m and the width of the room is w = 5.80 m. SubmitAnswer Tries 0/6
