2. A spherical mirror is to be used in a motion picture projector to form an
inverted, real image 95 times as tall as the picture in a single frame of film.
The image is projected onto a screen 13 m from the mirror. What type of
mirror is required, and how far should it be from the film?

-Spherical Concave mirror

-distance is 0.1368 m

Explanation:

-In physics, magnification is defined as the ratio between the size of the image to the size of the object;

This is also same as;

Given that m=95x, and and the image distance as 13m, the object distance is calculated as:

Hence, the object distance is 0.1368 meters

The image grows bigger when object is moved closer to the mirror, hence , this is a spherical concave mirror

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
