Answer:

a) q = -9.23 cm, b)  h’= 0.577 mm , c) image is right and virtual

Explanation:

This is an optical exercise, where the constructor equation should be used

        1 / f = 1 / p + 1 / q

Where f is the focal length, p the distance to the object and q the distance to the image

A) The cocal distance is framed with the relationship

       1 / f = (n₂-1) (1 /R₁ -1 /R₂)

In this case we have a rod whereby the first surface is flat R1 =∞ and the second surface R2 = -4 cm, the sign is for being concave

       1 / f = (1.60 -1) (1 /∞ - 1 / (-4))

       1 / f = 0.6 / 4 = 0.15

        f = 6.67 cm

We have the distance to the object p = 24.0 cm, let's calculate

       1 / q = 1 / f - 1 / p

       1 / q = 1 / 6.67 - 1/24

       1 / q = 0.15 - 0.04167 = 0.10833

       q = -9.23 cm

distance to the negative image is before the lens

B) the magnification of the lenses is given by

       M = h ’/ h = - q / p

        h’= - q / p h

        h’= - (-9.23) / 24.0 0.150

        h’= 0.05759 cm

        h’= 0.577 mm

C) the object is after the focal length, therefore, the image is right and virtual

Which mineral is commonly pinkish and has light-colored, wavy lines? A) quartz B) potassium feldspar C) pyroxene D) amphibole D)
Nina [5.8K]

Answer:

option B

Explanation:

The correct answer is option B

the mineral which is pinkish and light in color with wavy lines is potassium feldspar .                                                      

pyroxene is a mineral is typically dark in color generally it's color is  dark green.                                                                  

amphibole is also dark in color an is in green color.

olivine is a mineral which is in olive green color.

Quartz is a mineral which is light colored and it is also pink in color but it does not have wavy line.
