A dielectric material has an absorption coefficient of 0.25 cm−1. A plate of thickness 3 cm is made from this material, and light with intensity 20 W m−2 is incident on the front. Ignoring reflection losses, calculate the intensity transmitted through the plate. Give your answer as a decimal to 2 d.p.
