How does the light bulb invention influence us today?
The light bulb invention by Thomas Edison revolutionized society by providing a safe, reliable, and efficient source of artificial light. Today, light bulbs are essential in all aspects of modern life, from residential lighting to industrial applications, contributing to improved productivity, safety, and quality of life. The invention also laid the foundation for further innovations in lighting technology, such as LED bulbs, which offer even greater energy efficiency and longevity.
Why can't you see a light bulb when it is switched on?
The light emitted by the bulb overwhelms our eyes' ability to perceive its physical structure, making it difficult for us to see the bulb itself when it is switched on. Our eyes are more sensitive to the brightness of the light produced rather than the object emitting it.
How many 1.5 volt batteries does take to light up a big light bulb?
