According to Kirchoff's law, the one which is capable of emitting a particular wavelength is also capable of absorbing it. Hence Sodium vapour at incandescent state emits two yello-orance lines named as D1 and D2 lines
So as white light is passed through sodium comparatively cooler then it would absorb the same D1 and D2 lines. Their wavelengths are respectively : 5896 A and 5890 A
What else can I help you with?
What wavelength light does blue absorb?
Blue objects absorb wavelengths of light that correspond to other colors on the spectrum, typically orange or yellow. This means blue objects appear blue because they reflect blue light and absorb light of other colors.
What processes produce a different colors we see in Opaque objects?
The color of opaque objects is determined by the wavelength of light they reflect. When light strikes an object, certain wavelengths are absorbed while others are reflected to our eyes, creating the color we perceive. Different materials absorb and reflect light in varying ways, resulting in the wide range of colors we see in opaque objects.
What is the property of glowing under ultraviolent light?
The property of glowing under ultraviolet light is known as fluorescence. Certain substances absorb ultraviolet light and re-emit it at a longer wavelength, often in the visible spectrum, causing them to appear to glow. This phenomenon is commonly used in highlighters, black lights, and some minerals.
What are the everyday objects which absorbs the colors in sunlight?
All visible objects with a defined color absorb colours of the sunlight. If you see e.g. a red box, it absorbs all the green and blue parts of the sun light. While black objects absorb all colours (and therefore get most hot), white objects absorb almost nothing, so keeping cool.
Why do you perceive objects as white, black, or another specific color?
Objects are perceived as white, black, or a specific color because of the way they reflect and absorb light. Different colors are created when objects absorb certain wavelengths of light and reflect others, which our eyes then interpret as specific colors.
What wavelength light does blue absorb?
Blue objects absorb wavelengths of light that correspond to other colors on the spectrum, typically orange or yellow. This means blue objects appear blue because they reflect blue light and absorb light of other colors.
What objects can absorb water?
Objects that can absorb water include sponges, towels, clothes made of certain fabrics (such as cotton or linen), paper towels, and certain types of clay or soil. Absorbent materials have a porous structure that allows them to take in and retain water.
Why good absorbers are good emmiters?
Good absorbers of radiation are also good emitters because they can absorb energy from their surroundings and then emit that energy in the form of radiation. This is governed by Kirchhoff's law, which states that objects that absorb radiation well at a specific wavelength are also good emitters at that same wavelength.
What processes produce a different colors we see in Opaque objects?
The color of opaque objects is determined by the wavelength of light they reflect. When light strikes an object, certain wavelengths are absorbed while others are reflected to our eyes, creating the color we perceive. Different materials absorb and reflect light in varying ways, resulting in the wide range of colors we see in opaque objects.
What color does not absorb all wavelength of light?
Black is the only color that does absorb all wavelengths of light.White is the color that reflects all wavelengths of light.All other colors absorb only certain wavelengths of light and reflect the rest.
What is the property of glowing under ultraviolent light?
The property of glowing under ultraviolet light is known as fluorescence. Certain substances absorb ultraviolet light and re-emit it at a longer wavelength, often in the visible spectrum, causing them to appear to glow. This phenomenon is commonly used in highlighters, black lights, and some minerals.
Why do you see objects as different colors when light shines on them?
Because certain objects can absorb specific wavelengths of light(color) and they reflect the waves that they cannot absorb. the reflected wave of light is the visible color of the object.
Why red apple red?
We see colour because light is made up different wavelengths. Objects absorb certain wavelengths of light while reflecting others. An apple appears to be red because it reflects the red wavelength while absorbing all the other colours.
Do objects absorb water?
Yes, objects can absorb water if they are porous or have spaces within their structure for water to seep into. Materials like sponge, cotton, and paper are examples of objects that can absorb water.
Why are certain colors absorbed into some objects but not others?
colors are different frequencies of light. atoms in objects vibrate in specific frequencies too. objects with atoms vibrating in the frequency corresponding to the color absorb that color and reflect the other frequencies they can't absorb. the color of an object is basically the frequency of light that it can't absorb.
What are the everyday objects which absorbs the colors in sunlight?
