With reference to the Birefringence, consider the following statements:

Birefringent materials can exhibit different refractive indices in different directions.

Birefringence can be induced by applying physical stress or exposing materials to electric fields.

Which of the above statements is/are correct?

Question

Birefringent materials can exhibit different refractive indices in different directions. Correct: These materials have unique crystal structures that allow them to slow light differently based on the direction of propagation, leading to multiple refractive indices.
Birefringence can be induced by applying physical stress or exposing materials to electric fields. Correct: Physical stress or exposure to electric or magnetic fields can modify the birefringence of materials, affecting their optical properties.
