Answer:
Step-by-step explanation:
Some of the factors affecting intensity are: The energetic intensity of the source (the initial volume). The distance from the source (the volume at any point along the path). Any modifying elements in the light path (air, clouds, filters, reflectors, etc.) The factors affecting the intensity of light are diffraction.
Light has three properties: Wavelength, speed, and amplitude. The wavelength determines the type of light (color, etc.). Speed is determined by whether light passes through a vacuum or some material. The more photons emitted per unit time, the greater the intensity of the light. Directly, it is the power that determines the brightness of a bulb. That is why light bulbs have a power rating, i.e. a 60W bulb is enough to light a typical bedroom. But power is determined by the current and voltage which, in turn, is determined by the current.
