**Question 2 of 15**Consider a light ray that reflects off the interface between two transparent materials as shown below. If \(n_b < n_a\), then which of the following statements is true regarding the reflected ray?(Graph/Diagram Explanation: The diagram shows a light ray hitting the interface between two materials. Material \(n_a\) is on the left side and material \(n_b\) is on the right side. The light ray travels from the left towards the interface, where part of it reflects back into the material \(n_a\) and part refracts into material \(n_b\)).1. \( \quad \bigcirc \quad \) The reflected ray is in phase with the incident ray.2. \( \quad \bigcirc \quad \) The reflected ray has a lower frequency than the incident ray.3. \( \quad \bigcirc \quad \) The reflected ray is shifted in phase by \( \lambda /2 \) relative to the incident ray.4. \( \quad \bigcirc \quad \) The reflected ray has a shorter wavelength than the incident ray.5. \( \quad \bigcirc \quad \) None of the above
