Visible light
Photosynthetic organisms use light only under the wavelength of 400 to 700 nanometres. This is called as visible light spectrum. It ranges from vibgyor to red colour. Photosynthetic organisms have mainly chlorophyll in them which is green in colour. But maximum absorption occurs in red colour followed by blue and then green colour. Minimum amount of photosynthesis takes place in green colour and maximum amount takes place in red colour.

The extremes of the x-ray portion of the electromagnetic spectrum range from lambda = 1.0 times 10^-8 m to 1.0 times 10^-1.3 m. Find the minimum accelerating voltages required to produce wavelengths at these two extremes. V = For 1.0 times 10^-8 m, Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize...
