Detailed explanation-1: -To write the above numbers in scientific notation we can proceed as follows: 1) 300, 000, 000 ÷ 3.00 = 100, 000, 000 = 108 So we can write 300, 000, 000 = 3.00 x 100, 000, 000 = 3.00 x 108. The speed of light is 3.00 x 108 m/s.
Detailed explanation-2: -300, 000, 000 can be rewritten as 3×100000000 . Hence the scientific notation of 300, 000, 000 is 3×108 .
Detailed explanation-3: -(b) Speed of light in vacuum is 300, 000, 000m/s. Q. The speed of light in vacuum is 3×108 m/s. Sunlight takes about 8 minutes to reach the Earth.
Detailed explanation-4: -The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299, 792, 458 metres per second (approximately 300, 000 kilometres per second; 186, 000 miles per second; 671 million miles per hour).
Detailed explanation-5: -Light travels 300, 000, 000 300, 000, 000 meters per second. A light year is the distance that light travels in one year. Use scientific notation to express the number of meters traveled in one light year.
