1) What is the consequence of having denser and more spherical lenses (than human eye lenses). What are the advantages/disadvantages of this? (Hint: fish have them)

2) What is the advantage of being able to move lenses to different distances from the retina? (Hint: fish do this)

3) Many fish have a "tapetum" (a layer of reflective material just behind their retina). How does the tapetum interfere with high-resolution, crisp vision?

The electric flux passing through a spherical Gaussian surface of radius r = 1 m having a charge +q at its center is 175.353 Nm2/C. Now, we replace the spherical Gaussian surface with a cubical one keeping the charge at its center. If the length of the cube sides is d = 2 m, then the value of the electric flux passing through each face of the cube is ? Blank 1. Calculate the answer by read surrounding text. Nm2/C?
