The angle of incidence and the angle of reflection are measured from the B) normal to the surface.
Explanation:
Reflection is a phenomenon that occurs when a wave hits a boundary between two mediums and bounces back into the original medium.
The direction of the wave after reflection changes according to the law of reflection, which states that:
- The incident ray, the reflected ray and the normal to the surface all lie in the same plane
- The angle of reflection is equal to the angle of incidence (
In this framework, the two angles are defined as follows:
- the angle of incidence is the angle between the incident ray and the normal to the surface
- the angle of reflection is the angle between the reflected ray and the normal to the surface
Therefore, the complete sentence is
The angle of incidence and the angle of reflection are measured from the B) normal to the surface.

if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall.
We need it to help push out feet off the ground
Hope those helps :)
