| Waves that strike a surface that is transparent, like water, at an angle, there direction changes are called what? | Refracted
🗑

| What is reflection? | Reflection is the bouncing back of particles or wave that strikes a boundary between two media.
🗑

| What is the law of reflection? | The law of reflection states that the angle of incidence and the angle of reflection are equal to each other.
🗑
