Reply to discussion post on light
Hi John, I have liked your choice of concept of light as your discussion post, considering that light has turned as a basic necessity in the modern world. To add to your discussion, it is worth noting that light has different intensities and wavelengths. Generally, light intensities vary depending on their sources. There are specifically low and high light intensity bulbs, fixtures, and lamps (Pawlak & Zalesińska, 2017). For instance, high light intensity lamps emit a high intensity of light, whereas fluorescent lamps, which are said to be “cool,” offer a low intensity of light. Factors that affect the intensity of lights are diffraction. It is necessary to note that light possesses three properties: speed, amplitude, and wavelength (Pawlak & Zalesińska, 2017). Light wavelength determines its type, for instance, color. The speed of light is determined by the medium of transmission, which could be a vacuum or a particular material. The higher the amount of photons discharged per unit time, and so is the intensity of light emitted. From a broader perspective, it should be noted that power determines the bulb’s brightness. However, it is the voltage as well as current that determines power.
