Answer:
In computer graphics, attenuation is reduction or loss of intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, x- rays are attenuated by lead, and light and sound are attenuated by water.
Attenuation is the gradual decrease in energy as the X- radiation passes through absorbing material.
Intensity = power per unit cross scetional area
I = P / A
SI unit of intensity is Wm⁻².
