So, it will be [tex]1:4[/tex] ?
The intensity of light refers to the amount of energy being carried by the light waves per unit time. It is often measured in units of watts per square meter (W/m²) or in terms of the number of photons per unit area per unit time.
The intensity of light can be measured using a light meter, which is typically a device that measures the amount of light energy falling on a given area. This can also be calculated using the formula: Intensity = Power/Area.
This means that the first beam of light is carrying twice the amount of energy per unit time compared to the second beam. This could be due to factors such as a higher number of photons or a larger area being covered by the beam.
The intensity of light can be affected by various factors such as the source of the light, the distance from the source, the wavelength of the light, and any obstructions or filters that the light may pass through.
The intensity of light is important in many scientific and practical applications. It can help in studying the behavior of light and its interactions with matter, as well as in determining the proper amount of light needed for various tasks such as photography, lighting, and medical procedures.
