what does colour depend on frequency or wavelength?
Please, reasonably legible grammar and spelling are part of the Forum Rules, which you agreed to when registering.pratzzz said:im asking a basic question for optics . at a high school level k? wat m sayin is that if light depends on wavelenght so then when underwater y doesn't all colour outside appear different as acc to snells law light should change wave length .?
GrizzlyBat said:Yeah, I think it was wrong for me to say that the colour of light depends on frequency. Though that is what it looks like on those scales for electro-magnetic waves. And it is true that colours can look different depending on the shades of colours around them.
Jeff Reid said:Color are typically the perceived color of a combination of frequencies (and intentisies). Some colors cannot be duplicated with a single frequency. Most humans have 3 color receptors (some have 4), each which have bell curve shaped sensitivities to frequencies, centered about different frequencies, but these frequencies aren't exactly red, green, blue (or what ever the 4th receptor is with some humans).

Well, apparently you do since you did not understand what DaveC426913 said. Or is it just that you do not understand what "Forum Rules" mean. Yes, it is possible for people to puzzle out what you really mean. But a lot of people are not going to take that trouble so you are reducing the number of people who might answer you. And some people are just going to think that anyone that bad at English grammer aren't going to understand the answer anyway.pratzzz said:"Please, reasonably legible grammar and spelling are part of the Forum Rules, which you agreed to when registering."
I don't see anyone having a problem reading mate.?

You have come to the wrong conclusion.cybertific said:I agree that wave length and c are change depend on the medium. Wave length will be shorter in a denser medium such as water than in the air, but frequency will be same both in water and in air.
Thus, if color depend on wave length, then a color that we see in air and in water will be different. That color will be bluish in water, because wave length become shorter.
But if color depend on frequency, than that color will be the same. Because frequency doesn’t change.
The fact is we see different color. So the conclusion is color depend on wave length.
Colour depends on several factors, including the wavelength of light, the properties of the object being viewed, and the physiology of the observer.
The wavelength of light determines the specific hue of a colour. Different wavelengths correspond to different colours in the visible spectrum.
The surface of an object can absorb, reflect, or transmit different wavelengths of light, which affects the colour that is perceived. The chemical composition and structure of the object's surface also play a role in determining its colour.
The cones in the retina of the eye are responsible for detecting different wavelengths of light, which are then interpreted by the brain as different colours. The number and sensitivity of these cones can vary among individuals, leading to differences in colour perception.
Yes, external factors such as lighting conditions, surrounding colours, and even emotions can influence how we perceive colour. This is because our brains interpret colour based on context and personal experiences.
