The basic relationship between frequency of an electromagnetic wave and wavelength of the wave is
where
is the speed of light.
Manipulating the equation, we can rewrite it as
The frequency of the wave in our problem is
so if we use the previous formula, we find the correspondant wavelength:

Answer:
The z-component of the force is
Explanation:
From the question we are told that
The charge on the particle is
The magnitude of the magnetic field is
The velocity of the particle toward the x-direction is
The velocity of the particle toward the y-direction is
The velocity of the particle toward the z-direction is
Generally the force on this particle is mathematically represented as
So we have
substituting values
So the z-component of the force is
