Answer:

15 pm

Explanation:

Speed of a wave is given as:

Speed = wavelength * frequency

Since electromagnetic waves move at the speed of light, we can calculate the wavelength:

Wavelength = speed/frequency

Wavelength = (3 * 10^8)/(2 * 10^19)

Wavelength = 1.5 * 10^(-11) m

In picometre, pm, wavelength the is 15 pm.
