Dispersion is due to refraction.
In optics, dispersion is a phenomenon that causes the separation of a wave into spectral components with different wavelengths, due to a dependence of the wave's speed on its wavelength. It is most often described in light waves, but it may happen to any kind of wave that interacts with a medium or can be confined to a waveguide, such as sound waves. Dispersion is sometimes called chromatic dispersion to emphasize its wavelength-dependent nature.
There are generally two sources of dispersion: material dispersion, which comes from a frequency-dependent response of a material to waves; and waveguide dispersion, which occurs when the speed of a wave in a waveguide depends on its frequency. The transverse modes for waves confined laterally within a finite waveguide generally have different speeds (and field patterns) depending upon the frequency (that is, on the relative size of the wave, the wavelength, compared the size of the waveguide).
Dispersion in a waveguide used for telecommunication results in signal degradation, because the varying delay in arrival time between different components of a signal "smears out" the signal in time. A similar phenomenon is modal dispersion, caused by a waveguide having multiple modes at a given frequency, each with a different speed. A special case of this is polarization mode dispersion (PMD), which comes from a superposition of two modes that travel at different speeds due to random imperfections that break the symmetry of the waveguide.

What are the intermolecular forces of CH3CH2CH2OH?
London dispersion forces
What is the intermolecular forces of HBR?
The intermolecular forces of HBr are London dispersion forces and dipole-dipole interactions. London dispersion forces are the weakest intermolecular forces and occur between all atoms and molecules. Dipole-dipole interactions arise due to the polarity of the HBr molecule.
What are the forces on butane?
The forces acting on butane are London dispersion forces and dipole-dipole interactions. London dispersion forces are temporary attractive forces between nonpolar molecules, while dipole-dipole interactions occur between polar molecules due to the attraction of partial charges.
What type of intermolecular forces occur in highly volatile liquids?
Highly volatile liquids have weak intermolecular forces such as London dispersion forces. These forces are easily overcome, allowing molecules to rapidly escape into the gas phase, leading to high volatility.
What is the difference between dispersion forces and dipole- dipole forces?
Dispersion forces are formed between two non-polar molecules. These molecules form temporary dipoles. This creates a weak force. Dipole Dipole forces have a permanent dipole. That is the basic explanation
What is the intermolecular force for CBr4?
Dipole-Dipole and covalent sigma bond forces.
What is the weakest force of molecular attraction?
Dispersion forces
Does nitrogen has dispersion force?
Yes, nitrogen can participate in dispersion forces, also known as London dispersion forces. These are weak temporary forces that are caused by the motion of electrons within atoms or molecules. Nitrogen molecules have a symmetrical distribution of electrons, which can result in temporary dipoles and induce dispersion forces.
What are the intermolecular forces present in C4H10?
The intermolecular forces present in C4H10 (butane) are primarily London dispersion forces. As a nonpolar molecule, butane does not have dipole-dipole interactions or hydrogen bonding. The London dispersion forces result from temporary dipoles that occur due to fluctuations in electron distribution within the molecule.
