Which invention is often attributed to advancements during the 2nd Industrial Revolution?

The light bulb represents a significant advancement during the 2nd Industrial Revolution, which occurred from the late 19th century to the early 20th century. This era is characterized by rapid industrialization and technological innovations that transformed societies and economies. The development of the light bulb, particularly through the work of Thomas Edison, revolutionized the way people used and perceived artificial light.

Before the light bulb, illumination options were limited and often hazardous, such as candles and gas lamps. The introduction of electric lighting was not just a technological breakthrough; it fundamentally changed daily life by extending productive hours beyond daylight and increasing safety and convenience in homes and workplaces.

While the steam engine, textile loom, and locomotive were pivotal technologies, they primarily belong to the earlier phases of the Industrial Revolution. The light bulb epitomizes the innovations of the 2nd Industrial Revolution, highlighting the shift towards electricity and the impact of these advancements on modern life.
