Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. These waves combine to make white light. These waves are essential for photosynthesis. Who Am I? These rays have the smallest wavelength and the most energy of the waves in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear …

How does the color of light affect the rate of photosynthesis? _____ _____ Gather data: Set the Light wavelength to 400 nm. (The symbol “nm” stands for nanometers. A nanometer is a billionth of a meter.) Visible light ranges from 400 to 700 nm. On the TABLE tab, click Record data. Then set the Light wavelength to 420 nm, and repeat ...

The driving force for photosynthesis is light absorption by the photosynthetic pigments of photosystems I and II. Only the wavelengths of light absorbed by the photosystems can be used to drive photosynthesis. Light energy drives the flow of electrons from water molecules, which are split to form oxygen and hydrogen by a complex of proteins and metal ions associated with photosystem II ...

Wavelengths of Light That Are Most Effective for ...
A convenient way to investigate the effect of light colour on the rate of photosynthesis is to place a filter between the light source and the sample and an experimental set-up, using a blue filter, is shown schematically below. Using different filters for experiments is relatively simple to do and offers scope for a large number of potential investigations. The properties of the filter will ...

Wavelength (colour of light) affects the rate of photosynthesis. including information on absorbance and transmittance of known filters 1a. Light intensity (distance from a lamp) In this investigation, algal balls in hydrogen carbonate indicator solution are set at different distances from a suitable lamp for a set amount of time. At the end of this time period, the indicator solution is ...

For this reason, green light is not an effective color of light to power photosynthesis. Chlorophyll a and b together absorb light most effectively in the blue to violet range and the orange to red range. Since violet wavelengths have the most energy in the visible light range (due to their shorter wavelengths) they can provide the maximum energy for photosynthesis.

To measure the effect of wavelength of light on photosynthetic rate. To investigate starch production and storage in a single leaf . Introduction . Photosynthesis can be summarized in a fairly simple equation: 6 CO2 + 12 H2O ──( C6H12O6 + 6 O2 (1) Light. This reaction actually occurs in two phases. First, light energy from the sun is captured by the pigment chlorophyll. This first step is ...
