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.

Answer:
Electromagnetic wave
Explanation:
Snow days are announced on the by phoning the parents and guardians and also the news about a snow day can be broadcast on the television or radio airwaves or on the internet which are forms of electromagnetic wave transmission
An electromagnetic wave are oscillations of electric and magnetic fields which form electric and magnetic field vibrations
The direction of the oscillating electric and magnetic fields is perpendicular to the direction of propagation of the electromagnetic wave.
Answer:
Explanation:
Formula for AVERAGE acceleration
is Final Velocity
is Initial Velocity
is Final Time
is Initial Time
Most of the time, the initial time will be 0, so you won't have to subtract.
