Difference Between Violet and Purple: Understanding the difference between violet and purple becomes a crucial aspect of NEET preparation. While both colors are visually similar, their distinctions lie in the scientific understanding of light and wavelengths.
This explanation of the difference between violet and purple will lay the foundation for grasping concepts relevant to the NEET syllabus.
Violet color in the Light spectrum
In the visible light spectrum, violet is a color that corresponds to a specific range of wavelengths. The visible light spectrum spans from shorter wavelengths (violet and blue) to longer wavelengths (green, yellow, orange, and red). Violet light has shorter wavelengths compared to blue light.
Applications of Violet Light
Violet light, along with other colors in the visible spectrum, has several applications in various fields. Here are some significant applications of the violet color listed below:
- In fluorescence microscopy, violet light is utilized in biological and medical research. Fluorescent dyes are used to label and visualize molecules and cellular structures. Fluorescent dyes emit violet light when illuminated.
- In optical disc drives, like Blu-ray disc players, violet lasers are used. When compared to conventional red lasers, the violet light’s shorter wavelength enables a larger data storage capacity.
- High-speed data transmission in optical communication systems is achieved through the use of violet and ultraviolet light. These systems utilize shorter wavelengths to achieve higher data transfer rates.
- Dental curing lights use violet light to polymerize dental composites. The light activates the curing process, hardening dental materials used in restorative procedures.
- Ultraviolet (UV) light, which includes violet wavelengths, is used for sterilization purposes. UV light can kill or inactivate microorganisms, making it useful for disinfecting air, water, and surfaces in various applications.
- Violet light is crucial in astronomy for studying the properties of stars. Observations in the violet part of the spectrum provide valuable information about the temperature, composition, and movement of celestial objects.
Purple Color in the Light Spectrum
In the visible light spectrum, purple is frequently linked to a specific range of wavelengths in physics and optics. The visible light spectrum consists of various colors, each corresponding to a specific range of wavelengths. The colors of the spectrum, in order of increasing wavelength, are violet, blue, green, yellow, orange, and red (VIBGYOR)
Applications of Purple Light
- Purple light, which includes violet and blue wavelengths, plays an important role in optical communication systems. Fiber-optic communication systems use these shorter wavelengths to transmit information with higher data rates due to their shorter cycles.
- In semiconductors, the creation of purple LEDs (Light-Emitting Diodes) involves the use of semiconductor materials. Understanding the behavior of electrons and holes in these materials is essential for creating efficient purple LEDs used in various applications.
- Quantum mechanics experiments often involve the study of light and its interaction with matter. Purple light, being a combination of different wavelengths, can be used to determine the wave-particle duality of light and the principles of quantum superposition.
- Spectroscopy, the study of the interaction between matter and electromagnetic radiation, includes the analysis of different colors of light. Purple light, with its specific wavelength range, can be used in spectroscopic techniques to examine the properties of materials and analyze their composition.
- In high-energy physics experiments, researchers may use different colors of light to detect and measure particles. Purple light, along with other colors, might be used in detectors or imaging systems to capture the signatures of high-energy particles produced in experiments.
Difference Between Violet and Purple
Here you will get an overview of the difference between violet and purple based on various important parameters and perspectives. Take note of the given table.
| Difference Between Violet and Purple | ||
|---|---|---|
| Parameters | Violet | Purple |
| Definition | A spectral color with a shorter wavelength. | A composite color formed by combining blue and red. |
| Wavelength | Shorter wavelength in the electromagnetic spectrum. | No specific wavelength, as it is not a pure spectral color. |
| Composition | Pure color with no mixture of other colors. | Composite color resulting from the blending of blue and red. |
| In the Rainbow | Present in the visible spectrum of a rainbow. | Not a distinct color in the rainbow but may result from blending. |
| Nature | Often found in natural elements like flowers (e.g., violets). | Commonly seen in artificial or mixed sources, like fabrics or paints. |
| Associations | Can be associated with spirituality and calmness. | Often associated with creativity, luxury, and royalty. |
| Perception | Typically perceived as a more vibrant and bluer shade. | Perception may vary but is generally seen as a blend of blue and red. |
| Cultural Symbolism | May symbolize intuition, wisdom, or peace. | Symbolizes luxury, power, and creativity. |
Newton’s Explanation for the Colors of Light
During the 17th century, Sir Isaac Newton experimented with light and prisms, which resulted in his revolutionary discoveries regarding the properties of color and light. His explanation of the colors of light was one of his most important contributions.
In Newton’s experiments, a glass prism was used to collect sunlight, forming a spectrum of colors as a result. Here is a summary of Newton’s explanation for the colors of light.
- Newton observed that when white light passes through a prism, it is dispersed into a spectrum of colors. The spectrum consists of violet, indigo, blue, green, yellow, orange, and red.
- Newton concluded that the colors seen in the spectrum were intrinsic to light itself. He referred to these colors as prismatic colors.
- Newton identified the seven colors in the spectrum as primary colors. He noted that these colors cannot be further decomposed into other colors.
- Newton proposed that white light is composed of a mixture of all the colors in the spectrum. When passed through a prism, each color component is refracted by a different amount, resulting in the separation of colors.
- Newton’s work laid the foundation for the understanding of color addition. He demonstrated that combining certain colors of light could produce other colors through a process called additive color mixing.
- Newton also explored the idea that different colors have different refractive indices, meaning they bend by different amounts when passing through a medium like glass.
