how does wave frequency affect the light?
Light consists of particles on energy (quanta), the higher the frequency, the higher the energy.
This is called Plancks Equation, after Max Planck.
Energy=aConstant* frequency
Or do you mean the colour? If we take the usual spectrum

red (R) is at the low frequency end and violet(V) is at the highh frequency end.
The frequency of a wave has a major impact on how it behaves and interacts with its surroundings. In the case of light, the frequency of the electromagnetic waves that make up the light determines its color and properties.
The frequency of a light wave determines its energy and wavelength. Higher frequency light waves, such as ultraviolet (UV) and X-rays, have shorter wavelengths and carry more energy. On the other hand, lower frequency light waves, such as infrared (IR) and radio waves, have longer wavelengths and carry less energy.
When light interacts with matter, its frequency affects several important phenomena:
1. Absorption: At certain frequencies, matter can absorb light energy, causing the electrons in the material to transition to higher energy states. The specific frequencies that a material can absorb depend on its atomic or molecular structure, which determines the allowed energy levels and transitions. This absorption behavior is the basis of spectrophotometry techniques used in chemical analysis and the way objects appear to have certain colors.
2. Reflection and Scattering: When light encounters a surface or a medium with a different refractive index, it can be reflected or scattered. The interaction depends on the wavelength or frequency of the light. For example, shorter wavelength light (higher frequency) tends to be more easily scattered, giving rise to phenomena like Rayleigh scattering, responsible for the blue color of the sky.
3. Refraction: The refractive index of a medium determines how light is bent or refracted as it passes through it. The refractive index is dependent on the frequency of light, causing different degrees of bending for different colors. This effect is visible in a prism, separating white light into its constituent colors due to the variation of refractive index with frequency.
4. Interference and Diffraction: When light waves interact with each other, they can interfere constructively or destructively, leading to patterns of bright and dark regions. The ability of waves to diffract and interfere with each other depends on the wavelength, with shorter wavelength light exhibiting more pronounced diffraction effects.
In summary, the frequency of light waves influences their interaction with matter, determining properties such as absorption, reflection, scattering, refraction, interference, and diffraction.
