The source- gamma rays are emitted by the nucleus in decay, rays are generated when electrons accelerate 7 of 12 Estimate Radio Frequency 10^3 Hz 8 of 12 Estimate Visible Frequency 10^15 Hz 9 of 12 Estimate Gamma Frequency 10^24 Hz 10 of 12 Define Electromagnetic Wave A transverse wave. Propagating perpendicular electric (E) and magnetic fields (B). They are in phase with one-another. 11 of 12 Define transverse wave. A wave in which the medium oscillates at right angles to the direction of its propagation. 12 of 12
