Electrostatic image making<\/strong><\/p>\n<p>A photostat machine is a device that uses electrostatics to create a copy of an image. The machine works by charging a piece of paper with a negative charge. The image to be copied is then placed on the paper, and the paper is exposed to light. The light causes the charged areas of the paper to attract ink, which creates a copy of the image.<\/p>\n<p>Option A is incorrect because <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> electromagnetic image making is a process that uses electromagnetic waves to create an image.
