Chapter 24: Q12CQ (page 886)

Explain why people who have the lens of their eye removed because of cataracts are able to see low-frequency ultraviolet.

Short Answer

Expert verified

The people who have the lens of their eye removed because of cataracts are able to see low-frequency ultraviolet, because lenses absorb UV rays and prevent them from reaching the retina.

Step by step solution

01

Definition of frequency

The frequency is the quantity of waves passing through a location in a predetermined amount of time. The time duration has an inverse relationship with the wave's frequency. As a result, the frequency is the number of times a motion repeats itself inside a second.

02

People who have the lens of their eye removed can see low frequency UV rays

We know that the eye's lens absorbs ultraviolet light and prevents it from reaching the retina, which is sensitive to this frequency. As a result, if the lens is removed, UV light can reach the retina, and the individual who has their lens removed can perceive low-frequency ultraviolet.
