To analyze this situation, we need to use the principles of reflection.
When light is incident on a reflective surface, it follows the law of reflection, which states that the angle of incidence is equal to the angle of reflection. In this case, the incident angle is 30 degrees.
Since the wall is a perfect reflector, it reflects all the incident light. Therefore, the intensity of the reflected light is equal to the intensity of the incident light. So, the intensity of the reflected light is also I.
The angle of reflection is also 30 degrees, as per the law of reflection.
