What is accommodation?

What do you mean by power of accommodation?

If the highest modulating frequency of the wave is 5 kHz, the number of stations that can accommodated in a 150 kHz band width is

For a normal eye, the far point is at infinity and the near point of distanct vision is about 25 cm in front of the eye. The cornea of the eye provides a converging power of about 40 dioptres, and the least converging power of the eye-lens behind the cornea is about 20 dioptres. From this rough data estimate the range of accommodation (i.e., the range of converaging power of the eye-lens) of a normal eye.
