Whenerver a monochromatic light, say red changes medium, it reduces in speed which in turn reduces wavelength. But then if wavelength is reduced should not the colour change? Or dies it?
I think that the cone cells of the eye will detect wavelength rather than frequency - they are little antennas. The red light changes wavelength but not frequency when it passes through different media, but when it enters the eye, it travels through the Vitreous Humour in order to reach the Retina, and hence its velocity is standardised according the the permittivity of that medium.Zaya Bell said:Whenerver a monochromatic light, say red changes medium, it reduces in speed which in turn reduces wavelength.

Wavelength is directly related to the color that we perceive. Different wavelengths of light correspond to different colors on the visible light spectrum. This means that as the wavelength changes, so does the color that we see.
The relationship between wavelength and color is known as the "color spectrum." This spectrum is made up of all the different colors that can be seen by the human eye, and each color is associated with a specific wavelength of light.
No, two colors cannot have the same wavelength. Each color on the visible light spectrum corresponds to a specific wavelength of light, so if two colors appear to be the same, they must have the same wavelength.
The wavelength of light is measured in nanometers (nm). This can be done using a device called a spectrophotometer, which measures the different wavelengths of light that are emitted or reflected by an object.
No, the wavelength of light affects different colors differently. For example, shorter wavelengths of light (such as blue and violet) are scattered more easily by the atmosphere, which is why we see a blue sky during the day. Longer wavelengths (such as red and orange) are less affected by scattering and are able to reach our eyes, which is why sunsets appear orange and red.
