Which of the following statements is true?a)The angle of incidence is ...
Explanation:
The correct answer is option B: The incident ray, the reflected ray, and the normal drawn at the point of incidence lie in the same plane.
Incident Ray:
The incident ray is the ray of light that approaches and strikes a surface. It is the ray of light that is coming from a source and is incident on the surface.
Reflected Ray:
The reflected ray is the ray of light that bounces off a surface after striking it. It is the ray of light that is reflected back from the surface.
Normal:
The normal is a line drawn perpendicular to the surface at the point of incidence. It is a reference line that helps determine the angle of incidence and the angle of reflection.
Same Plane:
When we say that the incident ray, the reflected ray, and the normal lie in the same plane, it means that they are all in the same flat surface. In other words, if you were to draw these three lines on a sheet of paper, they would all lie on the same plane.
Explanation of Option B:
When light strikes a surface and is reflected, the incident ray, the reflected ray, and the normal drawn at the point of incidence always lie in the same plane. This is a fundamental principle of light reflection known as the law of reflection.
The law of reflection states that the angle of incidence is equal to the angle of reflection. This means that if the incident ray makes an angle of 30 degrees with the normal, then the reflected ray will also make an angle of 30 degrees with the normal. Both rays will lie in the same plane as the normal.
This principle holds true for any type of surface, whether it is smooth or rough, and for any angle of incidence. As long as the surface is reflecting light, the incident ray, the reflected ray, and the normal will always lie in the same plane.
In conclusion, option B is true because the incident ray, the reflected ray, and the normal drawn at the point of incidence always lie in the same plane according to the law of reflection.
The correct answer is option B: The incident ray, the reflected ray, and the normal drawn at the point of incidence lie in the same plane.
