tell you not to wear dark colors? The reason being is that dark colors absorb the more light, whereas light colors reflect light, which is why it gets so hot. The color white does not absorb any wavelength, instead it reflects them unlike the color black where it absorbs all of the light it can and reflects none. Light is a form of electromagnetic radiation that involves microwaves and radio waves.* The colors we see with our eyes are set apart by the wavelength that they are associated with. For example we see blue when the wavelength is between 420 – 490 nm. This follows the color wheel which shows the relationship between light absorbed and light reflected. (Rice, Finnegan,…).…

Light microscope is an instrument which used to magnify small specimen which cannot be seen through naked eye, by using a light source. It helps to magnify the small object to 1000* times than the real size of the real object.

Light Color and Photosynthesis Rate
How do the wavelength of visible light affect photosynthesis? Photosynthesis, a process used by plants and other organisms to convert light energy into chemical energy that can be released later to fuel the organisms’ activities, depends upon the absorption of light by pigments found in the plant leaves. Pigments, such as chlorophyll and carotenoids, absorb and reflect light based on the wavelength of light.
To be more explicit, photosynthesis…
2.4.3. Dispersion of Light
The fact that the refractive index different for each wavelength of light produces an effect called dispersion. This can be seen by shining a beam of white light into a triangular prism of glass. White light entering a prism is refracted in the prism at different angles depending on the wavelength of light.
The refractive index for the longer wavelengths (red) is lower than for the shorter wavelength (violet). This leads to a large angle of refraction for the longer…
Ghost Light is a play written and performed by Shawn Wright and directed by Thomas Morgan Jones. I attended the performance at Theater New Brunswick’s Open Space theater in Fredericton, New Brunswick on Friday November 25th 2016. The one-man show told the story of a boy native from Saint John, New Brunswick. That boy was in fact the actor himself, you were transported in his world through a heartfelt and authentic performance. The play as inspirational as it could be told the audience that it is…
With a p- value of 0.059229 between our red light treatment and our green light treatment, we fail to reject the null hypothesis and reject our alternative hypothesis because the value was higher than 0.05. Our alternative hypothesis was that red light would be more effective than green light on the rate of photosynthesis and our null hypothesis was that the color of light would not affect the rate of photosynthesis. Without enough evidence to support the alternative hypothesis, we…
How does light filtration affect the rate of photosynthesis?
Photosynthesis is an essential process plants use to convert light energy from the sun into chemical energy, released as glucose. Some of the limiting factors of photosynthesis include temperature, amount of light, the concentration of carbon dioxide, availability of water and the concentration of chlorophyll.

The world in which The Oresteia takes place is one where light and darkness are just two of many images used to enhance all viewpoints of the society that “Clytaemnestra” “Agamemnon” and “The Libation Bearers” occupy. The evolution is shown throughout the tragedy of The Oresteia, beginning in “Agamemnon”. The first play begins with the watchman noticing a signal fire upon a mountain, which lights up the night sky, therefore, alerting Argos that the Trojan War is finally over. Light and darkness…
energy. Sound and light are both disturbances in energy, and they both travel in the forms of waves. While sound travels in a longitudinal wave, light travels through a transverse wave. From a perspective of a human, sound and light on earth is very different compared to sound and light in space. These waves have differences in speed, form, shape, and other properties. Despite many of the differences, sound and light are very similar to each other.

Physics: Analogy of Light and Sound
Light and sound share many common aspects. Today, we will study some of notable similarities and differences between the two.
We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the…
