Hertz is units for frequency. (waves per second)
wavelength = speed/frequency

if you're given the speed use that to calculate, if not then you can probably assume it's a wave of light and use the speed of light (3x10^8 m/s) to calculate.

wavelength = (3x10^8)/(1.28x10^17)
= 0.000000002 m
= 2.34 nm

What is the movement of water up a narrow tube due to attractions with the surface of the tube called? capillary action meniscus
Shtirlitz [24]

The attraction mediated flow of water in the narrow tube has been termed as Capillary action. Thus, option A is correct.

The process of flowing up of liquid with the attraction force between the molecules and the surface has been achieved with the surface characteristics.

<h3>Movement of water in a narrow tube</h3>

The surface has the force of attraction with the flowing liquids in the sample. It results in the increased surface interaction, and the liquid flows up in the tube against gravity.

The movement of the liquid in the water through a narrow tube has been termed as capillary action. Thus, option A is correct.
