KembaraXtra-Psychology – Bunsen–Roscoe Law
The Bunsen–Roscoe law, also known as Bloch’s law, states that the effect of light on a photosensitive substance depends on the product of intensity and duration. Expressed as I × t = k, it indicates that a brief, intense flash can have the same photochemical effect as a longer, dimmer exposure. The principle applies to visual perception at very short durations and to photographic processes.
