Yes, that's correct.
The principle you're referring to is known as the Law of Reflection. According to this law, when waves (such as light waves, sound waves, or water waves) encounter a barrier, they reflect off the barrier. The angle at which they reflect (angle of reflection) is equal to the angle at which they hit the barrier (angle of incidence).
Here is a step-by-step explanation:
1. Definition of Angles: The angle of incidence is the angle between the incoming wave and a perpendicular line (normal) to the surface at the point of incidence. The angle of reflection is the angle between the reflected wave and the normal.
2. Law of Reflection: This is a fundamental principle in physics that states:
[tex]\[ \text{Angle of Incidence (} \theta_i \text{)} = \text{Angle of Reflection (} \theta_r \text{)} \][/tex]
3. Application: When a wave approaches and strikes a barrier, it bounces back in such a way that the angle measured between the incoming wave and the normal to the surface is the same as that measured between the reflected wave and the normal.
For example, if a light beam strikes a mirror at a 30° angle of incidence relative to the normal, it will reflect off the mirror at a 30° angle of reflection relative to the normal.
Considering this explanation, the statement that "Waves that collide with a barrier will reflect at an angle equal to the angle of incidence" is indeed _True_.
