Question

The angle at which light hits a surface (angle of incidence) and the angle at which it is reflected away (angle of reflection) are ____________.

always greater than 90 degrees.


always the same


always negative


always opposite

Answer 1

alwaye the same

Step-by-step explanation:

• Angle of incidence is called i
• Angle of reflection is called r
• sin i=sin r

Answer 2

are always the same

Step-by-step explanation:

angle of incident is equal to the angle of reflection i = r

the normal is perpendicular to the reflecting surface
