In winter a lake has a 0.35 m thick ice layer over 1.10 m of water. A light beam from above strikes a spot on the ice, making a 34 ∘ angle with the normal.

Part A

How far horizontally from that spot does the light ray strike the lake bottom? Express your answer to two significant figures and include the appropriate units.
