Path Of Light - Lab Report Example

Comments (0)
In a vacuum light travels at a speed of 3.0 x 108 m/s = 300,000,000 m/s (Lynch and Livingston 6). There are various sources of light with most of them being thermal. Light behaves like a particle and wave. Light has…

Path Of Light

Download file to see previous pages... A flash light is placed at the end of the row of the index cards and lit, after switching off the lights in the experimental room. The light can be seen passing through all the holes.
It can be concluded that light travels in a straight line. In the same way, the holes are in alignment and that since light travels in a straight line; it was observed passing through all the holes. The property of light travelling in a straight line is known as rectilinear propagation. Considering that the sizes of the holes are to be reduces, the light will continue travelling in a straight line but in a more restricted. When the cards were shifted a shadow is formed since the path of light is a straight line and does not bend around the object (Avison 2). Another direct effect of light’s path being a straight line is the casting of shadows by opaque objects.
The concept of the path of light being a straight line is applicable in various areas including the manufacture of mirrors both for domestic and industrial use, movie theaters that use projectors where light is restricted, cameras, human vision, and the casting of a shadow by light on opaque objects explains the formation of day and nights, as well as ...Download file to see next pagesRead More

Effects of Green and Blue Light on the Rate of Photosynthesis
Photosynthesis is the process through which green plants, algae, and cyanobacteria convert the sun’s energy into chemical bond energy of organic molecules that it consumes as food. This paper covers two experiments on photosynthesis; the first one investigates whether a positive rate of net photosynthesis depends on light levels.

Light experiment
Physical aspects deal with requirements such as light, moisture and temperature. The chemical aspect entails properties of pH levels, and mineral composition while biological involves the relation to other biological aspects such as animals and plants within the same habitat.

Effect of TGF- and Rock Inhibition on Phosphorylation of Myosin Light Chain
Effect of TGF-? and Rock Inhibition on Phosphorylation of Myosin Light Chain. Myosin light chains are distinct from heavy chains with their own properties. They are component of the macromolecular complexes of functional myosin enzymes. Phosphorylation of Myosin light chain (MLC) plays critical roles in several functions of cells such as smooth muscle contraction; motility and cellular morphogenesis (Chong et al., 2001).Determination of MLC phosphorylation is through balance between Rho-kinase activities and myosin phosphatase.

The Impact of Light Wavelength to Photosynthesis
With the assumption that the rate of photosynthesis as manifested by CO2 consumption would be inversely related to the received light wavelength, drops in CO2 recorded and data calculated. Green wavelength having the lowest rate of photosynthesis was the only data adhering to what we had predicted.

Does the Changing the color of light will affect the rate of photosynthesis
The control variable used was white light on the plant while green and blue light were the dependent variables. White light contains seven colors inclusive of blue and green, hence their dependency. White light was expected to

The effects of light and darkness on harvester ants and their ability to dig tunnels in dry and moist sand
There are various types of harvester ant species around the world (Tschinkel, 1999).pogomyrmex barbatus commonly referred to as red harvester ant is one of them (Lavigne, 1969). The established colony can be up to 10 thousand ants. It is well known that these ants
