Question

Select all that are true:

A) Precise observations using the plane mirror to confirm the law of reflection suggest that although the light is reflected from the rear surface of the mirror, the mirror must be positioned so that it's rear surface is moved slightly from the convergence point of the lines in order to account for refraction within the mirror's glass.
B) When viewed through the side of the tank, total internal reflection at an air-glass interface is the best explanation of why the fish at the bottom of the fish tank disappears. C)
As the incident angle increases for light striking the curved surface of the Plexiglas semi-circle, the internally reflected light beam increases in intensity. D)
When looking down into water, objects beneath the surface generally appear closer to the surface than they actually are. E)
Precise observations using the plane mirror to confirm the law of reflection suggest that because light is reflected from the rear surface of the mirror, the mirror must be positioned so that the rear surface of the mirror is exactly on the convergence point of the lines of your data form. F)
When looking down into water, objects beneath the surface generally appear deeper beneath the surface than they actually are. G)
As light strikes the curved surface of the Plexiglas semi-circle, the internally reflected light beam does not appear until the incident beam exceeds the critical angle. H)
When viewed through the side of the tank, total internal reflection at a water-air interface is the best explanation of why the fish at the bottom of the fish tank disappears. I)
When viewed through the side of the tank, total internal reflection at a water-glass interface is the best explanation of why the fish at the bottom of the fish tank disappears.
