Ultraviolet rays.<\/p>\n<p>Ultraviolet rays are a type of electromagnetic radiation with a wavelength shorter than visible light. They are invisible to the human eye, but they can be detected by special cameras and other devices. Ultraviolet rays can be used to detect forgeries because they can cause certain materials to fluoresce, or emit light, when they are exposed to them. This fluorescence can be used to identify counterfeit documents, such as passports and driver&#8217;s licenses.<\/p>\n<p>Infrared rays are another type of electromagnetic radiation, but they have a longer wavelength than visible light. Infrared rays can also be used to detect forgeries, but they are not as effective as ultraviolet rays. This is because infrared rays can be absorbed by many materials, which makes it difficult to see the fluorescence that is caused by them.<\/p>\n<p>Beta rays and gamma rays are types of ionizing radiation. They are much more powerful than ultraviolet and infrared rays, and they can cause serious damage to human tissue. Beta rays and gamma rays are not typically used to detect forgeries, as they are too dangerous to handle.<\/p>\n<p>In <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 <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> 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> conclusion, the correct answer to the question &#8220;Forged documents are detected by&#8221; is A.
