. To prevent many of them, a warning system covering blind spots is being developed. The system uses electromagnetic waves of frequency 2.4×1010 Hz. What is the wavelength of these waves?

Help pleeease? Thanks!

frequency is related to wavelength with the speed of the wave

v=λf

since you're talking about electromagnetic waves (light), we know the speed is that of light:

v=c=3.0X10^8 m/s

rearrange the equation and solve for wavelength (λ)

λ=c/f= (3.0X10^8 m/s)/(2.4X10^10 Hz) = 0.0125 m
