Which of the following technologies would produce the most energy in light waves? a. halogen lightbulb b. radio-controlled toy airplane c. microwave industrial drying equipment d. ultraviolet disinfecting wand

A

Explanation:

This is why we use halogen lightbulbs for lighting at homes. They produce visible spectrum of electromagnetic waves hence allowing us to perceive through sight in the dark. The tungsten in the bulb heat ups through electrical resistance that causes it to emit heat energy. The heat causes electrons to escape from the filament forming visible light.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
