Webasked Apr 18 in Physics by Somyek (121k points) Colour of light emitted by LED depends upon. A. its forward bias. B. its reverse bias. C. the band gap of the material of the semiconductor. D. its size. WebApr 7, 2024 · The higher the frequency,the shorter the wavelength. The equation that relates wavelength and frequency for electromagnetic waves is: λ ν = c. where. λ. is the wavelength, v is the frequency and c is the speed of light. So by these we can say that colour of light depends upon wavelength and frequency both. Hence option C is correct.

WebThe set of wavelengths absorbed by a pigment is its absorption spectrum. In the diagram below, you can see the absorption spectra of three key pigments in photosynthesis: chlorophyll a, chlorophyll b, and β-carotene. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color.
