Which of following statement is incorrect? A. Light absorption rate of a solid material is wavelength dependent. B. Light can penetrate metal if its frequency is lower than the plasma frequency. C. At a resonance frequency of an isotropic material, the transmitted light is substantially reduced. D.

Answer:

C and D

Step-by-step explanation:

An Optic axis of crystal is a direction in which a ray of transmitted light suffers no birefringence (double refraction). A uni axial crystal (example- calcite, quartz) is isotropic within the plane orthogonal to the optic axis of the crystal.

Hence, option A and B are incorrect and option C and D are options are correct.
