#lambda = 0.1m#

Explanation:

The equation for light waves is

#c = flambda#

where #c# is the speed of light, which is always #3xx10^8ms^-1# in a vacuum, #f# is the frequency and #lambda# is the wavelength.

We want to find the wavelength, so rearrange and put in values we know,

#lambda = c/f = (3xx10^8)/(3xx10^9) = (cancel(3)xx10^8)/(cancel(3)xx10^9) = 10^-1 = 0.1m#
