When it hits the wall at a height h from the bottom of the container; the light reflected off the wall falls a distance d = 20.0 cm from the wall on the bottom of the container The container is then filled with water (nwater 1333), and as it fills, the reflected beam moves closer t0 the wall due to the refraction of the beam passing through the water: When the water fills the container to just below h, the light beam is y = 1
