Keywords
💡Infrared Radiation (आईआर रेडिएशन)
Infrared radiation refers to the part of the electromagnetic spectrum with wavelengths longer than visible light but shorter than radio waves. In the context of the video, it is used to detect invisible spots on paper that are not visible to the naked eye. The script mentions using infrared radiation to enhance the visibility of certain features, such as spots on paper that were not previously visible.
💡Autograph (आटोग्राफ)
An autograph is a person's own signature or handwriting. The script discusses the use of infrared radiation to detect autographs on paper that are not visible under normal light conditions. This technique is important for verifying the authenticity of documents or artworks where the autograph might be obscured.
💡Chromatography (क्रोमैटोग्राफ)
Chromatography is a technique used to separate mixtures into their individual components based on their affinity to the stationary phase and the mobile phase. The video mentions chromatography in the context of analyzing ink on paper, which is a method to determine the composition of inks used in documents or artworks.
💡Visible Light (विसर्जन में जो वृद्धि होती है)
Visible light is the portion of the electromagnetic spectrum that is perceptible to the human eye. The script contrasts visible light with infrared radiation, indicating that certain features on paper can only be seen when illuminated with light from the infrared spectrum, not visible light.
💡Support (सपोर्ट)
In the script, 'support' seems to refer to a backing or a medium that helps in the process of detection or analysis. It mentions that the support becomes visible when using infrared radiation, which is crucial for identifying features that are not apparent under normal lighting conditions.
💡
💡Medium (मीडियम)
The term 'medium' in the script could refer to the material or substance used in a particular process, such as the type of paper or ink in the context of document analysis. It is mentioned in relation to the method of distraction and the use of infrared radiation, suggesting that the medium can affect how certain features are detected.
💡Kilogram (किलोमीटर ग्राम)
Although 'kilogram' is incorrectly mentioned in the script, it typically refers to a unit of mass. In the context of the video, it seems to be a mistranslation or mispronunciation. The correct term might be 'microgram' or another unit relevant to the measurement of substances in chromatography or other analytical techniques.
💡Filter (फिल्टर)
A filter is a device or medium that selectively passes certain substances while blocking others. In the video, a filter is mentioned in the context of paper printing, suggesting that it may be used to separate or identify certain components of ink or other materials on the paper.
💡Mobile App (मोबाइल एप)
A mobile app is a software application designed to run on mobile devices. The script refers to a mobile app that is used in conjunction with the paper analysis process. It suggests that the app might be an interface for viewing or analyzing the results obtained from the use of infrared radiation and other techniques.
💡Scar (स्कार)
In the context of the script, 'scar' might be a mistranslation or mispronunciation of a term related to the process of analysis. It could potentially refer to a mark or a trace left by a certain process, such as a scar on the paper from the application of a chemical or physical process.
💡Conditioner (कंडीशनर)
A conditioner is typically used in the context of hair care, but in the script, it might be used metaphorically or in a different context related to the preparation or treatment of paper or other materials during the analysis process. It could refer to a substance that modifies the properties of the paper to make certain features more visible or detectable.
