Hey there!
Answer:
A lightning flash involves tremendous electrical fields and currents, which oscillate between the earth and the clouds or between two groups of clouds.
In this electrical activity, many charges oscillate and produce a wide variety of electromagnetic waves. The flashes of light, we see, are emitted by atoms during this intense activity.
Those electromagnetic waves, which have frequencies in radio - wave range, interfere with the radio signals. Since, light and radio waves travel with the same speed, they arrive at the same time as does as light.
