The outcome of developing a properly exposed radiograph in a solution at 58 degrees Fahrenheit for 5 minutes is likely to result in underdevelopment. The reason is primarily related to the temperature of the development solution. Radiographic development processes are highly sensitive to temperature; they are designed to operate optimally within specified temperature ranges, typically around 20 to 24 degrees Celsius (68 to 75 degrees Fahrenheit).

At 58 degrees Fahrenheit, which is significantly lower than the optimal range, the chemical reactions involved in developing the radiograph occur at a much slower rate. This means that the emulsion on the film will not receive the necessary chemical action for a sufficient duration to fully develop the latent image. As a result, the image will lack contrast and detail, appearing lighter than intended, thus defining it as underdeveloped.

Understanding the importance of controlling both temperature and time is crucial for achieving the desired quality in radiography, which is why maintaining appropriate parameters is essential for proper image development.
