What effect did the colour filters blue and green have on the red yellow and pink flowers?
Explain the reasons for the change in colour
To understand the effect of color filters on flowers, let's first discuss how filters work. Color filters are transparent materials that selectively absorb certain colors of light while allowing others to pass through. Blue and green filters specifically absorb red and yellow light wavelengths. Now, let's see how this impacts different-colored flowers:
1. Red Flowers: When a red flower is viewed through a blue or green filter, the filter will absorb the red wavelengths present in the light that hits the flower. As a result, the flower will appear darker or even black when viewed through the filter since the red color is mostly blocked.
2. Yellow Flowers: Yellow flowers reflect mostly yellow wavelengths of light. When viewed through a blue or green filter, which absorbs yellow light, the flower will appear much darker or brownish. Similar to red flowers, the filter blocks the wavelengths that contribute to the flower's natural color.
3. Pink Flowers: Pink flowers typically reflect a combination of red and blue light. Since the blue filter selectively blocks red light, the color that remains is predominantly blue. Therefore, when viewing a pink flower through a blue filter, it will appear bluish or purplish. Conversely, when viewed through a green filter, which does not significantly influence the flower's natural color, the pink flower's appearance would remain relatively unchanged.
In summary, blue and green filters can alter the perceived colors of flowers by absorbing specific wavelengths of light. The impact on each flower depends on the wavelengths it reflects and the wavelengths absorbed by the filter.
