What happens when a red rose is seen in green light?
(i) Red rose in green light appears to be black. This is because the rose absorbs the green light falling on it and reflects none.
Why a red rose appears black in green light and red in white light?
The reason it appears red is because it reflects red colour and absorbs the rest. Hence whengreen light is shone on it, it absorbs all of the green light and not reflecting anything. Hence, itappears black.
Is red monochromatic light?
A pure red monochromatic light cannot look like anything other than red. So you will see a dim red light reflected by the blue object. Assuming a perfectly dark room except for the red light, the blue object under the red light will look about the same as a black object under the red light.
When sunlight falls on a red rose It appears red because?
Correct Option: B The colour of any transparent object is the colour of the light transmitted by it. A red rose appears red in white light because it absorbs all colours except red.
What color does red green flag appear when seen in green light?
Yellow.
When seen in green light the saffron and green portion of a Tricolour flag will appear to be?
black
When seen in green light, the saffron and green portion of our national Flag will appear to be black and green respectively, because saffron absorbs the green light completely without any reflection so is shown as black, but Green portion of the Indian national flag reflects the same green light which falls on it so it …
What color does green absorb?
Chlorophyll, the pigment that makes plants green, absorbs light in the red end of the spectrum and light in the blue end of the spectrum.
In which colour does a red flower appears in green light?
The red flower appears to be black in color because when green light falls on it all the color gets absorbed which shows that the flower is black in color….
What happens to the fringe width if monochromatic red light is replaced?
> If monochromatic red light Fringe width is proportional to the input wavelength. Thus if red light is replaced by the green light the wavelength of input light decreases. Thus Fringe width decreases. Option D is correct.
Why does monochromatic light emit only one color?
Since it only emits one color, monochromatic light has a single wavelength. Wavelengths are seen as a rainbow of colors when light is passed through a spectrum. Therefore, monochromatic light would emit just one of these colors. Should I hire remote software developers from Turing.com?
How does the wavelength of input light affect the fringe width?
Fringe width is proportional to the input wavelength. Thus if red light is replaced by the green light the wavelength of input light decreases. Thus Fringe width decreases. Option D is correct. Was this answer helpful?
What is the bandwidth of monochromatic light?
So, to the human eye, a light source with a bandwidth of 50 nanometers or less appears monochromatic. Monochromatic light is supposed to have all sorts of interference properties. Most of it is is wrong. It is based on the misconception that light comes in very narrow band (less than 1 Hz bandwidth) varieties.
