The speed of light is 3.0 x 10^8 m\/s. What is the speed of light in nm\/s?<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n To convert the speed of light from meters per second (m\/s) to nanometers per second (nm\/s), we need to use the fact that 1 meter (m) equals ( 1 \\times 10^9 ) nanometers (nm). Here’s how the conversion works:<\/p>\n\n\n\n So, the speed of light is ( 3.0 \\times 10^{17} \\, \\text{nm\/s} ).<\/p>\n\n\n\n The speed of light is a fundamental constant in physics, often denoted by the symbol ( c ). Its value in meters per second is ( 3.0 \\times 10^8 \\, \\text{m\/s} ). To convert this to nanometers per second, we need to recognize that a nanometer is a billionth of a meter. This means that there are ( 1 \\times 10^9 ) nanometers in one meter.<\/p>\n\n\n\n By multiplying the speed of light in meters per second by the conversion factor ( 1 \\times 10^9 \\, \\text{nm\/m} ), we effectively change the unit from meters to nanometers. Since we are working with exponents, we add the powers of 10: ( 10^8 ) from the speed of light in meters and ( 10^9 ) from the meter-to-nanometer conversion, resulting in ( 10^{17} ).<\/p>\n\n\n\n This conversion illustrates how changes in units can significantly impact the numerical value of a physical quantity, even though the actual physical speed remains the same. Nanometers are a much smaller unit of length, so the numerical value of the speed of light is vastly larger when expressed in nanometers per second.<\/p>\n","protected":false},"excerpt":{"rendered":" The speed of light is 3.0 x 10^8 m\/s.
