👉 In quantum mechanics, "deflectability" refers to a property of certain particles that can be used to change their properties or behavior. This is analogous to how light can change its direction when it encounters an obstacle. In other words, if you can tell which way the particle will go, you can influence its motion by adjusting its position or velocity. For example, a charged particle in a uniform magnetic field can deflect due to the Lorentz force, changing its velocity and position. Similarly,
