Chapter 35: Q.34 (page 1018)

The cornea, a boundary between the air and the aqueous humor, has a 3.0cmfocal length when acting alone. What is its radius of curvature?

Short Answer

Expert verified

The radius of curvature isR=0.76cm

Step by step solution

01

Given Information.

We have given that:

The focal length is3.0cm.

We need find out the radius of curvature.

02

Simplify 

By using formula:

n1s+n2s'=(n1-n2)R

From previous formula, Let us find R:

1∞+n2f=n2-n1RR=fn2-n1n2R=3.0×1.34-1.001.34R=3.0×0.341.34R=3.0×0.253R=0.76cm.

Here, n1and n2is the refractive index of the first and second medium respectively,fis the focal length andRis the radius of curvature.

A beam of white light enters a transparent material. Wavelengths for which the index of refraction is n are refracted at angle θ2.

Wavelengths for which the index of refraction is n + δn, where δn<<n, are refracted at angle θ2+δθ.

a). Show that the angular separation of the two wavelengths, in radians, is δθ=-(δn/n)tanθ2.

b). A beam of white light is incident on a piece of glass at 30.0°. Deep violet light is refracted 0.28° more than deep red light. The index of refraction for deep red light is known to be 1.552. What is the index of refraction for deep violet light?

A common optical instrument in a laser laboratory is a beam expander. One type of beam expander is shown in FIGURE P 35.29. The parallel rays of a laser beam of width w1 enter from the left.

a. For what lens spacing d does a parallel laser beam exit from the right?

b. What is the width w2 of the exiting laser beam?

A 2.0cm-tall object is 20cmto the left of a lens with a focal length of10cm. A second lens with a focal length of5cmis 30cmto the right of the first lens.

a. Use ray tracing to find the position and height of the image. Do this accurately using a ruler or paper with a grid, then make measurements on your diagram.

b. Calculate the image position and height. Compare with your ray-tracing answers in part a.

Mars (6800kmdiameter)is viewed through a telescope on a night when it is 1.1×108kmfrom the earth. Its angular size as seen through the eyepiece is 0.50°, the same size as the full moon seen by the naked eye. If the eyepiece focal length is 25mm, how long is the telescope?

A 15cm-focal-length converging lens is 20cmto the right of a 7.0cm-focal-length converging lens. A 1.0cm-tall object is distance L to the left of the first lens.

a. For what value of L is the final image of this two-lens system halfway between the two lenses?

b. What are the height and orientation of the final image?
