Explanation Black and White photographic paper are not much sensitive to light emitted by a bulb which appears red, because the bulb that appears red emits very little energy at higher visible frequencies. Color photographic paper is sensitive to all visible frequencies even to the frequency emitted by the bulb which appears red. Thus, red bulbs cannot be used in dark room for developing color photographic film...

Red bulb work in a dark room for developing black and white film and will it work for the color photographs.

Particle Theory of Light

The particle theory of light was the proposal made by Newton in 1704 in his treatise Opticks. This is the most basic light theory, in which light is thought to be made up of microscopic particles known as "corpuscles" and that's why this particle theory …

Stopping Potential

In an experiment conducted by Heinrich Hertz, an apparatus was made where the incident light was made to fall on the metallic plate, it was discovered that metals emit electrons. The surface electrons are bound to metals with a minimum amount of energy a…

Quantization of Charges

An electron is a negatively charged subatomic particle either attached to an an atom or sticks to the nucleus of the atom. Electrons exert the negative charge that tries to balance the positive charge of the nucleus.
