Webbthe interaction between a probe (a sharp tip attached to a cantilever) and the atomic surface of the sample. {The forces on the tip can be attractive or repulsive and cause the tip to deflect due to a change in these forces. This deflection is detected by the reflection of a laser beam shone on the back surface of the cantilever. WebbAnswer (1 of 5): Actually, it occurs all the time. But when the aperture/wavelength ratio is large, the spacing between fringes becomes too small, and the diffractive effects are unnoticeable. citizens advice minehead somerset
