#### Solution

**a, c and d**

**Explanation:**

Here we are given the frequency by which the charged particles oscillates about its mean equilibrium position, it is equal to 10^{9} Hz. The frequency of electromagnetic waves produced by a charged particle is equal to the frequency by which it oscillates about its mean equilibrium position.

So, frequency of electromagnetic waves produced by the charged particle is v = 10^{9} Hz.

Wavelength `λ = c/v = (3 xx 10^8)/10^9` = 0.3 m

The frequency of 10^{9} Hz falls in the region of radiowaves.
