What phenomenon is critical to the function of optical tweezers?
Gravity
Radiation pressure of light
Electromagnetic waves
Centrifugal force
Answer
Optical tweezers use the radiation pressure of light to trap and manipulate small objects. Radiation pressure is the force exerted on an object by a beam of light. It is proportional to the intensity of the light and the cross-sectional area of the object. Optical tweezers use a focused laser beam to create a high-intensity region of light.
