Problem

According to the present SI definition of the metre, how much time (approximately) does light in vacuum take to travel a distance of exactly

1\,\text{m}

? (Take

c = 3.00\times10^{8}\,\text{m}\,\text{s}^{-1}

.) a)

3.33\times10^{-10}\,\text{s}

3.33\times10^{-8}\,\text{s}

3.34\times10^{-9}\,\text{s}

2.99\times10^{-9}\,\text{s}
