Chapter 35: Q. 17 (page 1017)

A $6.0 m m$ -diameter microscope objective has a focal length of $9.0 m m$ . What object distance gives a lateral magnification of $- 40$ ?

Short Answer

Expert verified

The object distance is $4 m m$ .

Step by step solution

01

Given Information.

We have given that:

Diameter= $6.0 m m$ ,

focal length= $9.0 m m$ .

We need to find object distance which gives a lateral magnification of $- 40$ .

02

Equation.

$m_{o b j} = 40$

$L = 160 m m$

Object is not close to the focal point $S \approx f_{o b j}$ .

Approximation, lateral magnification is given:

$m_{o b j} = - \frac{1}{f_{o b j}}$ .

03

Calculation

$L = 160 m m$ represent microscope tube length.

Let us find the value of $f_{o b j}$ .

$f_{o b j} = \frac{L}{m_{o b j}}$

$f_{o b j} = \frac{160 m m}{40}$

$f_{o b j} = 4 m m$ .

A $2.0 c m$ -tall object is $20 c m$ to the left of a lens with a focal length of $10 c m$ . A second lens with a focal length of $5 c m$ is $30 c m$ to 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.

A reflecting telescope is built with a $20 c m$ -diameter mirror having an $1.00$ m focal length. It is used with an $10 \times$ eyepiece.

What are:

(a) the magnification?

(b) the $f ‐ n u m b e r$ of the telescope?

The Hubble Space Telescope has a mirror diameter of 2.4 m. Suppose the telescope is used to photograph stars near the center of our galaxy, 30,000 light years away, using red light with a wavelength of 650 nm.

a. What’s the distance (in km) between two stars that are marginally resolved? The resolution of a reflecting telescope is calculated exactly the same as for a refracting telescope.

b. For comparison, what is this distance as a multiple of the distance of Jupiter from the sun?

A common optical instrument in a laser laboratory is a beam expander. One type of beam expander is shown in FIGURE P35.29.

The parallel ray of a laser beam of width $ω_{1}$ enter from the left.

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

b. What is the width $ω_{2}$ of the exiting laser beam?

Two converging lenses with focal lengths of $40 c m$ and $20 c m$ are $10 c m$ apart. A $2.0 c m$ tall object is $15 c m$ in front of the $40 c m$ focal-length 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.
