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.

Most popular questions from this chapter

(a) Calculate the rate in watts at which heat transfer through radiation occurs (almost entirely in the infrared) from1.0m2of the Earth’s surface at night. Assume the emissivity is 0.90,0.90 ,the temperature of the Earth islocalid="1655871883893" 15°C, and that of outer space is 2.7 K. (b) Compare the intensity of this radiation with that coming to the Earth from the Sun during the day, which averages about800W/m2, only half of which is absorbed. (c) What is the maximum magnetic field strength in the outgoing radiation, assuming it is a continuous wave?

Laser vision correction often uses an excimer laser that produces electromagnetic radiation. This wavelength is extremely strongly absorbed by the cornea and ablates it in a manner that reshapes the cornea to correct vision defects. Explain how the strong absorption helps concentrate the energy in a thin layer and thus give greater accuracy in shaping the cornea. Also, explain how this strong absorption limits damage to the lens and retina of the eye.

Radar is used to determine distances to various objects by measuring the round-trip time for an echo from the object. (a) How far away is the planet Venus if the echo time is 1000 s ? (b) What is the echo time for a car 75.0 m from a Highway Police radar unit? (c) How accurately (in nanoseconds) must you be able to measure the echo time to an airplane 12.0 km away to determine its distance within 10.0 m ?

Give an example of interference of electromagnetic waves.

Suppose the maximum safe intensity of microwaves for human exposure is taken to be 1.00W/m2. (a) If a radar unit leaks 10.0 Wof microwaves (other than those sent by its antenna) uniformly in all directions, how far away must you be to be exposed to an intensity considered to be safe? Assume that the power spreads uniformly over the area of a sphere with no complications from absorption or reflection. (b) What is the maximum electric field strength at the safe intensity? (Note that early radar units leaked more than modern ones do. This caused identifiable health problems, such as cataracts, for people who worked near them.)
