Homework Help: Science - Waves - Sci. Notation

Posted by Jamia on Thursday, January 31, 2013 at 7:12pm.

I know that the formula to calculate the speed of light is c=fλ. F is the frequency, c is the speed, and λ is the wavelength. So how do I calculate the wavelength of a purple light with a frequency of 750 * 10^12 HZ. Frequency is measured in HZ. The speed is measured in m/second.

wavelength=speedlight/frequency
= 3E8/750E12 = 3/750 E-4 meters

work it out
