Question

Electromagnetic waves travel through space at a speed of 3*10^8 m/s find the frequency of the following. A) radio waves with lambda (a)=100 m (B) waves of red light (lambda (a)=750m (c) waves of Violet light (lambda (A)=500nm (d) microwaves with (lambda (A)=3cm (used in police radar) can someone help me how setup in math formula please

Answer 1

\[V=f \lambda\]velocity equal frequency times wavelength (lambda). Solved for frequency: \[f=V/\lambda\]This equation is the one to use. Remember to adjust ALL the wavelengths given to METERS because the given speed is in meters over seconds.
