What determines the color of a wavelength?
Building on prior answers, the facts are: Color is determined by the energy of the EM Wave that reaches your eyeball. Energy is defined as E=hf, where h is Planck’s constant and f is the light’s frequency. Thus, the color of an EM Wave is defined by its frequency.
What determines the color of an object give examples?
The wavelengths that are reflected determine the color that an object appears to the human eye. For example, the leaves appear green because they reflect green light and absorb light of other wavelengths. Therefore, the wavelength of the transmitted light determines the color that the object appears.
Why do objects reflect certain wavelengths?
Reflection and transmission of light waves occur because the frequencies of the light waves do not match the natural frequencies of vibration of the objects. When light waves of these frequencies strike an object, the electrons in the atoms of the object begin vibrating.
What is determined by wavelength?
Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. Wavelength is inversely proportional to frequency. This means the longer the wavelength, lower the frequency. In the same manner, shorter the wavelength, higher will be the frequency.
Does color depend wavelength?
The colour of visible light depends on its wavelength. Each colour has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light.
What determines the colors we see?
The human eye and brain together translate light into color. Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. By varying the amount of red, green and blue light, all of the colors in the visible spectrum can be produced.
What determines the color?
The ‘colour’ of an object is the wavelengths of light that it reflects. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws.
How is wavelength related to the energy of the colors of light?
The visible light portion of the electromagnetic spectrum shows the rainbow of colors, with violet and blue having shorter wavelengths, and therefore higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy (Figure 3).
What makes an object reflect certain colors?
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.
Why does an object reflect a certain color?
Does color depend on wavelength or frequency?
Frequency determines color, but when it comes to light, wavelength is the easier thing to measure. A good approximate range of wavelengths for the visible spectrum is 400 nm to 700 nm (1 nm = 10−9 m) although most humans can detect light just outside that range.
How are the wavelength and frequency of a color related?
Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. In the visual system, a light wave’s wavelength is generally associated with color, and its amplitude is associated with brightness.
What is the relationship between wavelength and color?
Answer Wiki. The wavelength is a property of the photon. The photon gets that wavelength depending on how it was emitted. The color you perceive it as is a property of your eyes and your brain. You have three overlapping sensors, roughly for photons in short, medium, and long wavelengths.

What is the wavelength of light that the human eye can see?
The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum, because humans can see it. Light outside this range may be visible to other organisms but cannot be perceived by the human eye.
What colors are in the visible spectrum of light?
The Visible Spectrum: Wavelengths and Colors. The spectrum of visible light includes wavelengths corresponding to red, orange, yellow, green, blue, indigo, and violet. Although the human eye perceives the color magenta, there is no corresponding wavelength because it’s a trick the brain uses to interpolate between red and violet.
