Reading Definition and 636 Threads

Reading is the process of taking in the sense or meaning of letters, symbols, etc., especially by sight or touch.For educators and researchers, reading is a multifaceted process involving such areas as word recognition, orthography (spelling), alphabetics, phonics, phonemic awareness, vocabulary, comprehension, fluency, and motivation.Other types of reading and writing, such as pictograms (e.g., a hazard symbol and an emoji), are not based on speech based writing systems. The common link is the interpretation of symbols to extract the meaning from the visual notations or tactile signals (as in the case of Braille).

    B Can a magnifying mirror or prism be used somehow as a low-tech reading aid for the visually impaired?

    The magnifying glass is widely used as a low-tech assistive device for reading by the visually impaired. As magnifying power increases, the lens diameter must decrease, greatly constraining the field of view. But a magnifying mirror achieves high magnification over a broader field of view, and...

    Why optical pyrometer gives a low reading?

    From my knowledge, the optical pyrometer determines temperature of a body based on the visible part of the heat radiation spectrum emitted by a body. Now the iron piece was red hot inside the furnace as well as outside the furnace, so it is emitting heat radiation in the visible part both while...
