because blue light has a higher absorbance by plant photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

Efficiency of an Incandescent Light Bulb Alex Mendez November 4‚ 2008 Purpose: The purpose of this lab was to examine the conversion of electrical energy to light and thermal energy as well as the efficiency of incandescent light bulbs. Procedure: To design this experiment we need to have a jar with water‚ temperature‚ and an voltage source. First‚ we poured 200 mL of water into a beaker then poured into a cup. We then stir up the water and measured the initial temperature of
