The 2014 Nobel Prize in physics was awarded to the inventors of blue LEDs. Consider the following statements in this context:
1. Gallium phosphate is the key ingredient used by the Nobel laureates in their ground breaking blue LEDs
2. Blue LEDs are used in high-speed networking, data storage, smartphones, water purification, and efficient home illumination.
Which of the above statements is/are correct?

Answer: [B] Only 2

Isamu Akasaki, Hiroshi Amano and Shuji Nakamura were awarded 2014 Nobel Prize in Physics for inventing blue LEDs. The trios used Gallium Nitride / Nitrate as the key ingredient in their ground breaking blue LEDs. LEDs are nearly twenty times as efficient as incandescent bulbs, and they aren’t saddled with the risky mercury-related health risks of fluorescent bulbs. As an added bonus, LED lights last longer, too. Blue light-emitting diode (LED), technology now used in high-speed networking, data storage, smartphones, water purification, and efficient home illumination.
