Illustrate the luminosity of the following. 1. A lamp and a bulb Question: what source has the highest luminous intensity? How about the least? Explain your answer.
Luminosity is a measure of the total amount of visible light emitted by a source per unit time, and is usually measured in units of lumens (lm).
1. A lamp and a bulb:
It's not clear whether you're referring to a specific type of lamp or bulb, but I'll assume you mean an incandescent light bulb and a standard table lamp with a single bulb.
The luminosity of a light bulb depends on its wattage, with higher wattage bulbs emitting more light. A typical 60-watt incandescent light bulb emits around 800 lumens, while a standard table lamp might use a bulb in the range of 40-100 watts, with a corresponding luminosity of around 500-1600 lumens.
Answer: Without knowing the exact wattage of the bulb and lamp, it's not possible to determine which source has the highest luminous intensity. However, in general, a high-wattage bulb or lamp will have a higher luminous intensity than a lower-wattage one.
The least luminous intensity source will be a source that emits little to no visible light. For example, an infrared heat lamp that emits primarily infrared radiation, which is not visible to the human eye, would have a low luminous intensity.
