The speed of light is now defined to be 2.997 924 58 x10^{8} m/s.

Express the speed of light to (a) three significant figures,

(b) five significant figures, and (c) seven significant figures.

Step 1

Power of 10 is not significant. So only 1^{st} part is need to be considered. Every digit after decimal point is significant.

Step 2

a)

Speed of light in three significant figures will be 3.00×10^{8} m/s.

Step 3

b)

Speed of light in 5 significant figures is...
