Paperback. Condición: New. Print on Demand. This book investigates an objective physical standard for defining white light, also known as gray, based on the Planckian distribution of energy required to elicit the hueless sensation. The author found that white light may be described theoretically by light from a Planckian radiato…r at approximately 5000 degrees Kelvin or, practically speaking, by average noon sunlight at Washington, DC. However, the author emphasizes the need for a more extensive statistical investigation to establish such a standard. The book also includes a thought-provoking discussion on the desirability of an extensive statistical determination and correlation of the characteristics of vision. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
