The human eye is sensitive to a range of wavelengths within the electromagnetic spectrum, and different wavelengths correspond to different colors. The visible spectrum spans from shorter wavelengths (associated with violet and blue colors) to longer wavelengths (associated with red and beyond). Here's how changing the wavelength can affect the light you see:
Color Perception:
Shorter Wavelengths (Blue/Violet): Shorter wavelengths are associated with blue and violet colors. As the wavelength decreases, the light appears more towards the blue end of the spectrum.
Medium Wavelengths (Green/Yellow): Medium wavelengths are associated with green and yellow colors.
Longer Wavelengths (Orange/Red): Longer wavelengths are associated with orange and red colors. As the wavelength increases, the light appears more towards the red end of the spectrum.
Intensity and Brightness:
Generally, the perception of brightness is more strongly influenced by intensity rather than wavelength. However, changes in wavelength can affect the overall color appearance, and our eyes may perceive certain colors as more or less intense.
Color Mixing:
Combining light of different wavelengths can result in color mixing. For example, combining red and blue light can produce magenta, while combining red and green light can produce yellow.
Interference and Diffraction:
Changes in wavelength can also be associated with optical phenomena such as interference and diffraction. These effects can result in patterns of colored fringes or bands, particularly when light interacts with fine structures or passes through narrow openings.
Scattering:
Shorter wavelengths of light (blue and violet) tend to scatter more than longer wavelengths (red and orange). This is why the sky appears blue during the day; the shorter blue wavelengths are scattered in all directions by the gases and particles in the Earth's atmosphere.
Absorption:

What is the wavelength of mercury light?
The wavelength of mercury light can vary depending on the specific emission line, but typically falls in the ultraviolet range between 365 to 435 nanometers.
What happen to wavelength when you vary amplitude?
Changing the amplitude of a wave does not affect its wavelength. Wavelength is the distance between corresponding points on a wave and is determined by the frequency of the wave and the speed at which it travels through a medium. Amplitude, on the other hand, represents the height of the wave and does not impact the wavelength.
What does a wavelength carry?
A wavelength carry energy. Strictly speaking, a wave carries energy. A wavelength is a property of a wave.
What is the wavelength for copper?
The wavelength of copper can vary depending on the context in which it is being considered. In the context of light, copper does not emit visible light, as it appears as a metallic color. In the context of electron microscopy, copper can exhibit a wavelength of around 0.02 nanometers when accelerated to high energies.
How does the speed of light depend on the wavelength?
The equation relating the velocity, wavelength and frequency of an electromagnetic wave is given byv=f λwhere v - velocity of the em wavef - frequency of the em wave andλ - wavelength of the em wave------------------------------------------------------------------------------------------------It is so important to know that velocity of light depends on the nature of the medium and does not depend on the wavelength.
What is the wavelength of mercury light?
The wavelength of mercury light can vary depending on the specific emission line, but typically falls in the ultraviolet range between 365 to 435 nanometers.
Can you explain the relationship between absorbance and wavelength in a graph?
In a graph, absorbance is typically shown on the y-axis and wavelength on the x-axis. The relationship between absorbance and wavelength is that as the wavelength of light increases, the absorbance generally decreases. This is because different substances absorb light at specific wavelengths, so the absorbance of a substance can vary depending on the wavelength of light being used.

What is wavelength og light?
Visible 'light' ranges from roughly 380 to 750 nanometers (billionths of a meter). It can vary somewhat for different individuals' eyes. If electromagnetic radiation has a wavelength longer than about 750nm or shorter than about 380nm, you may still call it 'light' if you want, but the human eye doesn't respond to it.
How does the speed of light depend on the wavelength?

What happens when light and its wavelength travels from one medium to another?
When light travels from one medium to another, its wavelength may change. This is known as refraction. The speed and direction of light may also change depending on the difference in refractive indexes between the two medium.
Is all light the same, regardless of its source, whether it be from the sun, a light bulb, or any other origin?
No, light can vary in its characteristics depending on its source, such as intensity, color, and wavelength.
Which describes an electromagnetic wave?
A transverse wave consisting of changing electric fields and changing magnetic fields
How is speed affected of the frequency or wavelength changes?
-- Changing the frequency/wavelength has no effect on the speed. (Notice that all electromagnetic waves, from wavelengths of perhaps 10-19 meters to perhaps 1,000 kilometers, travel with the same speed.) (Also notice that if the baritone sax plays a note together with the female vocalist, then you hear them at the same time, no matter how far from the stage you're seated.) -- Changing the frequency causes the wavelength to change, by the same factor in the opposite direction. -- Changing the speed causes the wavelength to change, by the same factor in the same direction.
What is the wavelength of invisible lights?
The wavelength of invisible light can vary depending on the type of light. For example, infrared light has wavelengths longer than those of visible light, ranging from about 700 nanometers to 1 millimeter. Ultraviolet light, on the other hand, has wavelengths shorter than those of visible light, ranging from about 10 to 400 nanometers.
