(a) The diameter of Saturn at its equator is approximately ×1.21105 kilometers. Write this number in standard notation. (b) An astronomer\'s infrared telescope is able to detect radiation with a wavelength of 0.00000621 meters. Write this number in scientific notation.
(a) Kilometers:
(b) Meters:
Solution
(a)
diameter = 1.21*10^5 km = 121000 km
(b)
wavelength = 0.00000621 m = 6.21*10^-6 m
Let me know if you have any doubt.
