Duration: 8 min 17 s
Description: In this lecture, we discuss the concept of contact angle and capillary length. We derive the relation for contact angle in terms of surface tensions between different phases. We also discuss how capillary length can be imagined as a screening length over which interface perturbations vanish.

In this lecture, we continue our discussion on filtering of signals and its relation with convolution. In the previous lecture, we discussed the low-pass filter. In this lecture, we extend our discussion to highpass, bandpass, and notch filters.
