Light is a form of electromagnetic radiation that enables us to see the world around us. Different types of light are characterized by various wavelengths and colors, and one such distinction is between yellow and white lights. Both types of lights have unique properties and uses, and understanding their differences can be beneficial in various applications.
Color Appearance: The most apparent difference between yellow and white lights is their color appearance. Yellow light has a wavelength of around 570-590 nanometers (nm), making it closer to the longer end of the visible spectrum. White light, on the other hand, has a blend of multiple wavelengths and appears colorless to the human eye.
Energy Consumption: In terms of energy consumption, white light is more energy-efficient compared to yellow light. This is because white light is generated by combining all the colors of the visible spectrum, while yellow light is produced by a specific frequency. Therefore, more energy is needed to produce yellow light compared to white light.
Visibility: Yellow and white lights also differ in terms of visibility. White light is considered to be brighter and more visible than yellow light. This is because white light has a higher contrast against darker backgrounds, making it easier for our eyes to see. Yellow light, on the other hand, is less intense and can be challenging to see in certain situations, such as foggy or sunny conditions.
