Which of the following sources of information is received by the user in visual mode only?

The source of information that is received by the user in visual mode only is a photograph. A photograph is a visual image that can convey information without the use of words or sounds. Unlike television, radio, and computers, photographs do not have the ability to transmit audio or textual information. Instead, they rely solely on the visual content captured within the image to communicate information to the viewer. This makes photographs an effective means of conveying information that is primarily visual in nature, such as the appearance of a product or a scene in nature.
