Question

the correct sentence among the following is_______A) incident ray and reflected ray lie in the same plane and normal lies in the other plane B) reflected ray and normal lie in the same plane and incident ray lies in the other plane C) incident ray reflected ray and normal all lie in the same plane D) incident ray and reflected ray and the normal all lie in different plane​

Answer 1

Answer:

From the laws of reflection, we know that

The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence, all lie in the same plane.

Hence, the correct answer is OPTION B.

Answer 2

1. There are two statements in the law of reflection: first one is that the angle between the incident ray and the reflected ray is always equal and the second one is that the incident ray ,the reflected ray, is normal and the point of the incident lies in the same plane. So, the correct answer is " normal and same ".

2. The INCIDENT ray,REFLECTED ray, REFRACTED ray and the NORMAL at the point of incidence all lie in the same plane. The plane is referred as plane of incidence.

3. The INCIDENT ray,REFLECTED ray, REFRACTED ray and the NORMAL at the point of incidence all lie in the same plane. The plane is referred as plane of incidence.

4. From the laws of reflection, we know that

The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence, all lie in the same plane.

Hence, the correct answer is normal and same.

its the answer...
