Question

In setting up an experiment for a high school biology lab, you use a concave spherical minor produce real images of a 4.10-mm tall firefly. The firefly is to the right of the mirror on the mirror's optic axis, and serves as a real object for the mirror. You want to determine how far the object must be from the mirror's vertex (that is. object distance s) to produce an image of a specified height First you place a square of white cardboard to the right of the object and find what is distance from the vertex needs to be so that the image is sharply focused on it. Next you measure the height of the sharply focused images for five values of s. For each s value, you than calculate the lateral magnification m. You find that if you graph your data with s on the vertical axis and 1/m on the horizontal axis then your measured points fall close to a straight line. According to (Figure 1). starting from the position that you calculated in part C, should you move the object closer to the mirror or farther from it to increase the height of the inverted, real image? What distance should you move the object in order to increase the image height from 8.00 mm to 12.00 mm? Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

Part D :

CLOSER is the answer

this can be explained in the part E

Part E :

the magnification is " m "

m = - 12 / 4.1

m = - 2.9268

1 / m = - 1 / 2.9268

s = - 25 X ( - 1 / 2.9268 ) + 25

s = 8.5417 + 25

s = 33.541 cm

so it is closer
